but it certainly not with animals theory so we're on slide going through the examples we haven't really started on the examples yet why
don't normal gasses for diatonic molecules so we can sort of touched on this 1 already but let's hope so we drop while a couple of these diagrams 1 to give us some practice your remind you of how to do it and choose to do this explanation of the IRA fiery after on an exam I would probably ask you to give me some reasoning for it that would involve the BMO diagrams so we incident laughter quickly now I wanna go a little bit more in depth so let's just look at a couple of examples with sink the 1st 2 since that's really all we able the deal with so far so let's look at helium neon just so that we can hear uses to explain so 1st of all for helium new and drop the diagram we always job the atomic orbitals too it's not correct if you don't have the atomic orbitals you notice I can brackets instead of dotted lines honestly it's just because I have a hard time going perfectly straight line timing get a little messy at the brackets near cleaner but it really makes difference up like that are now labels don't forget to label everything alignment and the nine-year atomic orbital area atomic energy level diagrams of the 1st don't do that here so this will be a 1 1 as with all charts need the label actually is so we're gonna label and say that the energy now we have to decide what we have here so we're combining levels and when we get out of that so I made labeling but whatever that was started Snow Maiden said you have to put the substantive so I really think it's a little tiny doing some scripts of something smaller you select subscripts was 1 because it comes from the 1 authority of suffer a basic outline now how many electron Sicilian normally have just 1 million you can call it that now if only only have to worry too much about where everything comes from we just we have from electrons will we have 4 so we started lower high low 1 2 3 4 at any of the need to do to make this diagram complete there were so let's look at this as 2nd now and say well why would this would this not form we formulae 2 plus didn't look like the Bangor and Cumberland over ways of looking at this the off the most formulaic way is to say Well it's 1 half times by the bonding electrons minus the entire bonding so we'll figure that out so it's 1 one-half How many levels and bonding er how many electrons and binding levels we have 2 great just from here and in harmony entire binding just from the ones that the star search to so what monitor 0 the 12 in the bottom 0 desire the forming a bond that sofa that noble gas is not going to be a about so it's not going on that now Of course at this point you're always saying only do the same thing but let's go ahead and make it just for extra practice so let's just do Bailey so I only want them to only 1 then equals 2 levels so if we do that we 1st have to drop out are atomic orbitals with Sunday the at 2 to Western to us In some type balance securely get a job after that and it was too little now we have to sort of make some decisions you so down here if we combine these
what are we going to get 2 orbitals quarrels urinals 2 1 of the 5 on below where the names signal and signal star with the 2 US labeling and the bottom so since airlines getting small to us and to ask summer and now we have to make some decisions when we come up here we know that we're going to have how many of molecular orbitals 6 but we have to make a decision about which 1 is going to be the wall is the same 1 that the law is the pylons criminal in this case a sister so remember that certain that thought that happens between of nitrogen and oxygen so oxygen Florian neon are going to have this pattern we're here said Monday on the outside the top and bottom and over the subscript down here now is the need to pee because it comes from the PPE and here to P because it comes from the fuel In usable prize and don't forget the start of the year by bond area into a binding model and then the subscripts will be to peace Kentucky however so we have Sigma two-piece stock prior to the start to the segmented no people last doesn't matter how far the energy levels are part because of my slide from last week you know I showed you that makes diagram of the all laid out in a should you where they were kind of you know incrementally going down and and slipping With the bottom to drivers and doesn't actually matter so long as you do right I can't I can't ask you to gage you put these closer than these or something like that the only way too hard to gage and it's kind of on the scope of this class the only reason I showed all those little differences in the energy levels when I showed it to you on the slide was so that you can get that idea that you had that these energy levels it wasn't just a hard flip-flopping between that nitrogen and oxygen that it was sort of a greedy its where happens flat paint but it's far drawing these don't worry about where the energy levels are now some I is for an annual ending I breaking up measuring sticks are anything but these should about equally across from the piece that should be about the same distance is that this should be about the same distance is that an end goal out the measuring stick but the rulers but you make it look about like this you don't want your P or bills the way period pure bills he went here they should be in the Senate just like here are to asses the kind of in the center of a to signal a pact so just how did it affect us much of that's the only thing I can say is that you're atomic orbital should be in about the center of the energies of snow development so how many valence electrons nearly half so we sell it all in so of course when we go to do this we have that and if we figure bond order there well we had the exact same number nodding were orbitals event had bombing again so we can often come and say how on bonding models too for 6 months and then too 4 6 8 Serb underwater is once again so if I ask you well why doesn't like a light on the is a noble gasses diatonic Eleanor diatonic molecules and ask you use loaded theory to explain it in another way to explain of course you can just use the sort of free mid-term to logic select the stuff that we learned during the term 1 period and say Well that's sealed because they have a full village shall stable and last season most theory to explain it you could say Well it's because the Bonda 0 so she would make us you would see that you have no Justin Ruiz explained the same sort of phenomenon collectors so and diagram shows Bond a 0 lot of work to get back on serve but you know is going review I sort of wanted to do something you want Dynamo diagrams and doing it from scratch that this is a sort of ammo diagram that you will be expected to be able to do next Friday part which species had longer bond lengths until 0 2 so this is again falls under the category of there's a couple of different ways you can figure this out there couple different ways you can explain it however let's go ahead and explain it with there so now that we have had dramas from scratch a few times I'm a cheap for the sake of time and move back to the slide on it so let's look at 0 2 it ends into since those that's when I asked you to look at but so were looking into noted and were saying which 1 has longer bonds so model we know about what if we have a really if we have a triple what started back and have a short bond length a long bond short right it's going sure it's everything forces or so a single bond would have a a longer but they seem basically just link them in order of their bond work so far I observer oxygen you have a bond order of 3 cheers in a bonded to hear so which ones the near longer on accident oxygen only longer Major-General be sure that again if I exercise after I ask you to draw level diagram to you but you would just be able to draw but so for carbon monoxide I think that warbles combine in a way where the energy is high Sigma Pi starts so I told you the order of the energies and I say dropping Ammo diagrams and then after the monitors said this is the way that I would go ahead and I would ask you to draw a diagram of a federal Nuclear died on Aug 2 differently so let's go ahead and just drop from scratch most simulating it's the practice we have it up on the board to but I would rather do it from scratch so I
say CEO it's a long demo diagram I had to tell you the ordering so now we know of that we can set up a diagrams to look like that of will cover normally looks like Tracy Pi Sigma 5 think that ordering comes from what I told you on the side of it comes from the fact they say that the ordering is priced in 1 hour pipes servicing stock your pilots will always go with the the 2 the 2 articles so now we'll throw in the label everything just like before we don't forget to draw axioms where label or atomic orbitals and we don't really put all scripts so to us down here and to P for all of these so and now we can select from a mail slot France's current 4 the carbon side with before now how many electrons as oxygen 6 Sunday accident site was put 6 so now I'm going back to what the question assets as a job the emo diagram and tell me the bond or so this sedition the diagrams of fire now needed the electrons in the Senate we don't really have to wonder where the electorate is coming from here we just have to know how many we have so we have to work with for further comment 6 the accidents on so we just started the low-energy and work our way out we don't care whether they came from the cobbler whether they came from the oxygen we just start down here so we have now so now what is the bond so we have to kind of everything their bonding orbitals all electrons and everything that the into binding intervals sold by minerals 1st 2 4 6 come in area and another where have we know something's on demanding as little star so which are the only 1 that had the start here that had electrons and this so how many elections so what is abundant so the C I can ask you with the monetarism asking to use them a diagram to explain it now while we're here and we have a lot talk about Ohio 1 more time to see the sort of cement that so if we want to make this just because they don't necessarily want to redraw the adamant we tried to make this a negative stance so new problem with the makers of steel minus so how would we do that how can we make this a seal minus add another electric rates so now now as that will make this a seal minus new makes you might want actually and every drawing this just for the sake of your notes but it did not want to add a natural front that will diagram part of it's kind of easy place where in this case Europe electrons next the the 1st that we can so we can put it in here so we'll just put it in here not the decision about where we're going put it as far as the atomic diagrams go beyond an undercover antioxidant an electron so we're going it's the 1 that won support from the doesn't once electrons was another word for wanting electron density lecturing utility so where would we you wanna put it on the most electrifying nearly selected most of which it is Mexico so we discovered added now let's look at what that does to the bond order so before we bother calculating which will do this and let's think about what we do we added an electron to abandon or in demanding and demanding rate 7 start so we are added to antibiotic that is going to add to monitor takeaways Nevada tentacle areas in tight binding it stops it from bonding as well now do that in abundance is gonna go up about down anyone on given how much can 1 2 3 half rate in electronic address syntax half of about because that's it you take it takes to electronics make about so gas before he fell into the Formula One is akin to being provided to play fact packed with 8 of fast using formula we are but will check it so now we have 2 4 6 8 in a bonding orbitals an end to the story and intent on and so we had to .period so is a reminder on how I don't work every example of using high-handed in Ohalloran nuclear situation where you have to decide where the electrons go here here OK and if we were to do the pluses what would be have done adding electoral take away on Friday I chose you minus here mostly because of it was simpler to do do on the page all accident questioned here if we weren't in the plot where I take any electron away over here would be taken the current accident the common right you're taking away from the least electronic so keep that in mind too I think so that an that flight this just shows the same thing that we just as I can make sure you're certain differentiate that we added in a problem here the next flight is sort of a checklist you think that while grading exams everybody forgets to do when drawing a more diverse so keep
this in mind when you're going through in your dining when you're done drawing 1 on the exam I mean who knows if you have an examiner off but you know when you're not drawing 1 the exam may change activities the new label all the atomic orbitals that 1 after the other 1 S 1 to S into peace but the referee appointed as the new label the molecular orbitals did you at the start of the entire binding models that not appoint you wanna lose this right because he forgot to add the stars make sure you add the stars all the entire bonding models do you Addison tracked electronic appropriately if you have an IOC don't forget thanking you and I and you need to make sure you go back and you say Well I haven't actually electron or Havel at 1 life electron when you're drawing these duties a proper order for the rules for the animals so anyway that is the issue of where you have oxygenated and the yen oxygen the accident fluorine neon having 1 source and then all of the 1st ones having a different watering with heighten Sigma .period that's what I you that some just keep canceled checklist in your head of things you need to go back and check every time you do it all and in along with stalled familiar subscript and I want to know where they come from the come from 1 after the company to us company to sometimes when you see these you'll also see the piece with a different label that explains the I don't really care about that I'm 1 of those referring to let's talk about it minute but it's talking your Accies right whether year-on-year era ex-wife disease it I don't think that matters South quite as much weaker demand the mind-set you actually see that no 1 says you have to say accidents certain way so I don't I'm not bothering with that too much other still being done an example of this already but now I want actually talk about it a little bit more in depth and don't get too bothered by this equation yet noisily on and because of that so when we were adding and subtracting bills were homeowners then I have contacts and things that had the same Adams bonded together H 2 I asked to go to all of those although the war also are in P oral someone oxygen differ in energy from the bureau's of a different oxygen now right why would they be any different than the center on the same pattern there had the same energy level now what did think just taking a gas if we take ,comma in we take oxygen are those energy levels well let's think about notes how would you know less than will always have that we really sort of done energy level calculations was when we did the right way and we can do the Advani gleaned from these because they have lots of electrons and that that doesn't work but when was the library played we get the same energy levels for something like hydrogen and helium not all right because we had been there residency in there we had to figure that in the calculation had disabled the so even just a 1 electron system is the energy levels of something like an oxygen let's stick with lithium on lithium and hydrogen the same no so what do we think that carbon and oxygen is energy levels and the same no this factors into on word at when we're trying to figure out where these models are packed so if we have appeal and they just drawn as 1 line which I don't really love and it really kind should be 3 lines just is 1 for the sake of saving space in assuming that you know but there's 3 plurals and same thing here they may add a little differently and so what you end up getting is this huge mishmash but where all these orbitals fall into well this is not something that I need I want you to replicate it's just something that I want you to sort of understand soul out if you have a polar covalent bond they're going to be shared differently than if you have a non-political they'll bond that's what I want you to get out of sleight of hand so for that section of the book this is the main reason I bring this up I just know that for all of these sorts of situations where you have a political will abandon the shared differently than unknown Paula Quayle and non-political they'll bond that all I really care that you get from the section of the book for now if you go on a physical chemistry you'll learn a lot more about this but just for now know that they don't have the same way that with this equation right here said they all had the same way and Morgan of leave it at that for now any time that I ask you to do what he's had removed their diatonic I'll tell you the ordering of the energy I'll do what I did this year when I say that for the pure metals get this theory about and so that's all you'll need know that not sapling does it as well if you even hopefully going through and doing a sapling work they did the same thing I think you have to figure out NO NCL at some point in their homework and they'll tell you the order in those say here said my here's applies here is this year's that and you'll just fell in the electrons it's the same way for the now summation mentioned years since we ought to doing it anyway because there's a whole section of the book where you have this sort of thing worked out for water and benzene and a few other ones when I don't worry about Holly atomic ions in and out of Titanic molecules and animal theory that really goes beyond the scope of this class so don't worry about that section of the book it's interesting and if you're going to go on in chemistry even into organic you should skim through it and you should look at but it's not going to be tested I think we do need to be able to do for the exam you have to be able to do the whole nuclear died comics from scratch your hand you blank sheet paper and a Johnny oxygen and tell me something about it your finding the bond order that you have to be able to do for the harem nuclear diatonic all apologize the energy levels or I'll just tell you the ordering the way sampling does that and then you'll be able to drop from the ordering and all your electrons make sure you know how do I with both of the state both of these are Ireland's affair gave cemetery know how to do that OK so moving on to Chapter 5 if you independently iteration of the notes print out you may have some extra slides and there just castles out but so Chapter 5 only covered 5 . 1 2 5 . 6 in this class all the rest is indeed taking care of and 1 B and think it's the 1st thing you in 1 detail but there is a section of this chapter that works really well with what we're talking about with died holes in covalent polar covalent molecules and things of that sort it really works better at this sort of fit it into their before moving on and Celestyna recovery here so it's just the 1 section so what we're going to get into here and you kind In view of mine shaft tear into thinking about what we're talking about when we're talking about the guy pulls and what makes a molecule Paula because we're really sort of doing a 180 out in about here or back to Lewis
structures and articles of so in the heart of this chapter that we wanna talk about here is what isn't intermolecular forces so let's break down the word because most things in science you sort breakdown down the wording in an idea for what's happening injured it's between different things right Internet is between different things what is the word from between something that's the same within 1 thing and try so that'll come up here and there but where was talk about in molecular forces so keep that in mind that in turn is between different things molecular as really molecules say so intermolecular forces going to be forces between 2 different models that so and that's the idea that you had to different molecules and those 2 different molecules are going to interact with each other and they're going to have to interact with each other in different ways depending on what those molecules on properties or not all molecules are going to interact with each other the exact same way but so we have a bunch of different types of forces that were going to be talking about here so the 1st I always sort of covered up until now mostly is intramolecular forces the thereupon there with a molecules so that's where this becomes entrapped these Vatican will announce we already talked about this is not really a huge amount in this chapter that we're talking with the intramolecular forces here the intermolecular forces now we have a bunch of new ones and these are all going to be weaker than covalent back because they are not as relatively stable right if you have this covalent bond form you to really do something to break apart the reason that foreigners because it was more stable no intermolecular forces these are much much weaker these are going to be a little bit more transients of you'll have them but they're they're going to be switching between different molecules on so the therefore for different ones as is normal I sort of have always stood out for you here we're going to go into each 1 in more depth in a minute but we're going to have dipole Dybul forces wouldn't have hydrogen bonds which is actually just a really particular type of provide full force all of and then we have and I pulled in dispersion force so that you want to get out all these different slides is what sort of molecules will form these particular ones what type of strength still looking at because not all of these are going to be the same strength In will also get into the idea of what is that going to do to it's sort of both properties for instance boiling point melting point what's going to change about things of that sort based on these forces 1st we want talk about that political forces on Sunday if attractive forces between polar molecules so if you have to if you have a polar molecules this is a sort of course you can get so if I would ask you does this molecule has a debt that had died will forces the 1st thing you ask yourself is what is that Paul and if the answer is yes Waldman has died Bible forces if the answer is no more than dozen Bible Bible force now the winner these work is a kind of you can think of it as always in these molecules being little tiny magnets if that hasn't died for that knew that once I had a positive charge in 1 side has a negative charge so much is the positive side of 1 molecule go wanted due to the molecules around attracted magnified positive steps that it's positive it's going up all the negative side toward it is going to push the positive side away from and so what happens is they were the sort of attracted to each other because of now these are some of the isn't going to be the strongest except for hydrogen bomb so hydrogen bonding is actually where you have hydrogen bonded to particular Adams haven't ridiculously strong like that in that little general area and so it's sort of an extension of the dipole vital force idea so this is going to have increasing strain strength as the dipole the molecule increases 1 that so that is if we have a molecule that really really Paula and we have a molecule is not very poor no 1 has really really Paula is going to have more dipole Bible forces effect Our and actually seemed to confuse looks like that so wedding we do something there what I mean by that it is let's say we have something like most of the Celica line structure since you haven't had a lot of practice aligned structures Simeon that the parents Of the river on the policy we have that so what I meant by way comparing the dipole dipole forces and their strength is the 1st you would have to decide which 1 has a higher Bible 1st of all do we think that each of these is going to have a guy I politely Paula so we have carbon In 3 ages a carbon the carbon 3 agents don't fear rules for line structures so let's draw this out a little bit expanded in case you've forgotten how your line structures work would have In another here sorry precious we would have that right that sort of expanded out don't forget how to do that that was the thing that kind of sent home as homework lectures on in a video so you can review that as much as you like so what we think would have led to that employer bonds 1st of all at the 1st question the carbon to the oxygen that area the 17th amounts to the Browning so we get a dipole going toward the more polar the more Elektra negative ads right we know that the polar bonds because we're looking at the different selected negativity was saying that have a high electric utility that has elected its Hi Elektra negativity
about so now to decide which 1 has more I forces would have to decide which dipole a stronger so which 1 more elected negative side trying to set this up as close as possible to the same sort of Adam which ones more elected negative oxygen oxygen so which 1 would have grated apple onstage so it should have more dappled courses the so that's what I mean years increasing strength of the bible of the molecule increases let's do 1 more example an even simpler now action elite level I'm so this sort of sums the Bible that will force so that is something that the bank will force you say that polar or more likely I'll give you an atom and our molecule what sort of intermolecular forces have annual sales Hill doesn't have a dipole yet so I have Bible Bible forces and so the next woman Maria talk about and if we take this to the extreme hydrogen
bonds so little is known about of oxygen nitrogen in exploring where special about those 3 Adams that has something to do with this His very high electric utility right history highest on reactive now so something happen if you take any bonds of hydrogen to that oxygen nitrogen Florida and what happens is you get something called hydrogen-bonding what's really important here is to notice what is and isn't the hydrogen bomb this is an entire molecular 4 straight into the work so that means between the same molecule or within 1 molecule or between different markets different molecules so 1 molecule of water in another molecule of water 1 molecule of ammonia another molecule ammonia or 1 each either way so what happens here is you get hydrogen that is covalently bonded so that means you have an actual want something like this bond in water that's covalently bonded so this hydrogen in this oxygen or covalently bonded to each other no if you take hydrogen and you bonded to an oxygen nitrogen fluorine in other words the 3 most operators Collins you'll get you'll have a Adam a molecule that is capable of hydrogen bomb but don't forget it's occurring between 2 different molecules no so right here let's look at this as 2nd before a move on if you have the what to water molecules near each other that is not happening with dozens of working Is that your oxygen molecule is going to have a little bit of a negative charge rate because oxygen is very highly elected again it's stealing the electron density away from this hydrogen that's right here so you get a little bit of a negative charge here a little bit of a positive side a charge here so what'll happen is just like in the Bible that will forces you'll have this attracting today we have a negative attracting to the Providence and then we can draw also want to these and say well you have a positive year attract that to another Adams negative and other Adams positive and this kind of zigzag all around but if I draw you this and I say point to the hydrogen bonds in you .period Odessa unity of points know that is a covalent bond that is not a hydrogen bomb this is the hydrogen bomb the high it's not really a real bond right it's this intermolecular forces so this hydrogen bond is between 1 Allen's positive about the positive side in another molecules Delta negative side had to make sure the EU you remember that 2 different molecules now something like ammonia can do it too where you have any each year and each year and each year so you have these 3 bonds you hydrogen altered on a little bit of a positive charge your oxygen area they shouldn't take so little bit of a negatively charged and the negative side of the nitrogen would be attracted to other sides of the other if if we were just looking at ammonia other positive sides other ammonia and molecules on their money market now I put this picture and so you can see that you don't actually only had the hydrogen bonding between exactly the same those molecules you might have if you have a mixture of ammonia and water in some situations and you can actually get them hydrogen bonding to each other that's fine now the more hydrogen donors and acceptors the higher the difference and event so this means something like water where you have is going to be it's going to have a real at a very high amount of hydrogen bonding or maybe something that doesn't have as many hydrogen-bond orders or sectors would have left In you have some really big examples of that when you get to 0 your worksheet weakened offering you can circle all the places where it's possible the hydrogen bomb in your discussions the moratorium
on donors and acceptors you have the higher the difference and properly so this is what I was talking about in that last little section I just sort of 1 with bit more so here we have ball stick models where all of these gray areas are carbons low-carbon Papelbon carbon from carbon and then the red diarrhea oxygen In the wake hydrogen but doesn't give away representing molecules I thought I'd put up for you see so what we're gonna do here at the end of various say while all of these different forces effective boiling point the more forces you have the more your boiling points affected so something like this molecule How many hydrogen owners accepted as you have this section we have a hydrogen and hydrogen and hydrogen that's bonded to an oxygen so 3 and you have an accepted here except a few minutes after when he makes up
during donor this bill hydrogen that being sorted donated to the sponsors the donor this is the acceptance so here we have 3 notice you really really high boiling point 290 degrees Celsius here how many do we have to write 1 here no 1 here and we have a little below boiling .period shirts so high that it's lower than this 1 now we look at water where we just have to have the donors and there's the 2 Paris arguably to acceptance but you have left the so we go from 1 of these situations Tszyu history and we go from 100 to 180 to 209 event so we have exactly talked about this boiling point phenomenon detail yet but this is how we're assorted decide which ones have more intermolecular forces is which ones have the higher boiling point so wouldn't next so the last few types of we have to order get through which were obviously definitive today but let's talk about unifil forces now and this was very similar to dipole dipole except now you actually have an actual in there instead of just 2 molecules of the died so and we have Hi I'm doing things that interact with a polar molecule was shot when thinking that it again right if we have positively charged ions what is that going to do to the negative side of another market it's going to attract and negative ion it's going to come to repel the negative side so whenever you have a situation like this a positive ID checks the negative side In negative ion attracts a positive sign
the business was specifically so this is
very similar to a dipole dipole forest now can't take note here this is normally can occur and what sort of situation 1 compound to compounds 2 compounds raided a good example of this were you also has invited money going on but it's something like salt and water is unwise is also easily in what is you have positive ions and had negative ions in those positively charged negatively charged ions in the sodium chloride the water is going to come in and around that and it's going to make it really easy to actually dissolved salts so
this is sort of 1 of the reasons why this year like dissolve like
