what we have had a great weekend harbor any questions alright so my my policy is the due date for sapling is 2 days after we finished lecture so that means that a of the due date for Chapter 22 Wednesday right so somebody has to remind me that I'm worried I'm worried I'm going to forget because I'm going to be on a majority of mystery medicine competition today so I might yet also so we have to send in another environment is sincere or not everyone plays fair and lasting yes Wednesday morning it was time to about 1 that I needed follow-up on that yes OK Cimmino to remind me of my mind's missed analysis right outside bank are so we left out last time talking about since Tuesday and we had to different routs that we decided that if we're any you see out there would be better not to use the lithium grouse better use green years so let's branch off here about money well spent that would we decided it
would be better not to use the on lithium Ralph facility because they will add flights so we wanted just to at once so we're going to do for renewed instead of really do the other half restaurant flying out were under is going to be more than 1 pathway and so that makes trading trickier on exams so you really want to make sure when you get your exam back some people if they don't do well they won't look at their exam and you know you might have things marked wrong that were correct if fighting if you have a unique pathway that I didn't anticipate the might've policy that you did definitely gonna make sure that you aren't checking out I want you to get the points that you deserve all right so that we do C O 2 while age through classes this is a little bit longer halfway but we don't hear songs it gives us what we want but would probably decided to make that and there were no idea we are reduce their carboxyl a gas into and alcohol so we could use all the aluminum hydride Step 1 followed by the average to 0 To give us the product so that's 1 step longer doesn't matter as long as you get the right product questions about the synthesis anybody yes he's absolutely yet so it needed to do the same thing here so this could be a rather than originally record also no problem that are writes also that the 32 is devices synthesis of find comfort from comments having 4 or fewer apartments alright so this one's a little bit more complicated were complicated our carbon skeletons here so so wants popping Anthony immediately is that their carboxyl aghast at the C O 2 age groups arm-in-arm illegal reticence retro synthetically here and I I know I can make it that same strategy we just did here so integrated and then we have C O 2 and we follow that way I'm adding acid to make carboxyl gasses OK and the careered I can make from corresponding I'll kill him lies and then I can make that paralyzed from the corresponding alcohol so we we all of a sudden in this chapter have gotten much more sophisticated in the things that we can synthesize when we were building down carbon shelters before it was all using the protonated settling I was a little easier to see this is a little harder to see all right so but we know we have a bunch ways of making alcohols this chapter certainly green yards in a good way of making alcohols and we have to have 4 or fewer occurrence so what I'm thinking is is that we can we have with CDs you know 1 2 3 4 thinking if we break right here and this is 1 2 3 for those are 2 4 carved pieces so hounded out later makers born right here and then make respond by you doing and making a gray-bearded and attacking an elder Hyde so and again there's more than 1 way to do this but that is certainly a method that will will will work so that make this using an elder hired so the alcohol side would be the elder and then this sign would just be a greenery or lithium was just make it lifting here OK so that's what I would look like each each carbon is 4 pieces and Olivia reagent unlike can certainly make from the corresponding uphill here alive In oddities from here all right everybody falling at that time Richardson Greta synthesis let's write out the synthesis of the forward direction so that's sort of the thought process that goes with there that we have before we write up the synthesis of the 4 direction on the exam we don't great thought because it's too difficult to great so the deadly 1 right after synthesis in the forward direction all right we could have made inured also they're interchangeable for this reaction so there's a I'm for carbon held high we follow that with water that gives us the alcohol relocating for and then when we wanna do there to turn that into Internet and bromide would be years the therefore security I would not want use HBR here because things are going to rearrange a novel we won here 3 carrying "quotation mark turn that into a alliance such show that we can make a greener or get a list nearly all we want to no we deftly Wannamaker granted here and because we're going using a steel tube that makes the Green Years of this would be a reaction were I'm call open-ended and you have to write that the products from each step but probation steps you can include armed with the the previous reagents so then we would have this O 2 not too many of these types they're very difficult to grade I usually have things in a box with an arrow and fill in each step questions anybody on that said synthesis of pretty sophisticated arms is definitely what we wanted to use we want practice practice practice during services yes question you could start with you again with him just where the direction set amid says only organic compounds you would want to make with ,comma prepare his defense or any other questions yes it it it yes certainly and it should be a secure plus right actually on I can make a big deal about this yesterday to where said the water is not strong enough right that's more correct OK more questions yes OK yes you can use magnesium you don't have to use all of the major there you can make is to its tender like printers better right you guys like Prince better people use there's more often than anything and that's perfectly fine OK so that is the end of Chapter 28 where is
starting 21 alright so
this is all about in this chapter Oregon and talk about reversible reactions of Type 1 carbon meals in the next chapter talk about reversible reactions of type 2 carbon you play there were going to get to the more complicated copy of him alright so I just did a similar ideas above that wiped out the jobs of aldehydes Type 1 a reportage we have everything we recognize this compound here testosterone but admitted that this room knowing and progesterone here so we have some steroids here but this is glucose opened change will talk about open shade include endowed glucose that's coming up in the very last check this quarter the last chapter of him so that's open chain form of glucose see the elder and on advertising Jones figure prominently in in of perfume manufacturers that use little or no small really good on this feels like pistachio this month smells like camphor we have maraschino cherries for the elder Hyman said now than I was smells like cinnamon we got raspberry flavoring without the knowing which smells amazing news that this quarter in my lab it's the whole at malls like the knowledge is nice oil of violence and then we have loved this compound here where the different in its all differently but we have as spirit for 1 of the Union's servers and Caraway for the other Indians were so the receptors in the nose trial so these are going to smell differently nomenclature balancing the towns were in await seller on next chapter to do our nomenclature has a right now organist shell that preparation and I think those of the sections you wanna review Chapter 21 6 a and B. we just had that right so we need to do their
physical properties of alleging he Jones will jump right in here so here's some comments with similar molecular weight -minus 6 . 9 do not need to memorize these numbers were just talking about trends here Alden Life several regularly held 20 degrees centigrade 56 for the key tell that makes sense because it's got a 1 work carbon so as we increase molecular weight we increase boiling point and hear similar molecular weight but this 1 is 82 . 3 degrees centigrade why is that when so much higher calling .period hydrogen-bonding yeah OK so this 1 here user hydrogen-bonding sectors only so that means that these guys when you put in water they can hydrogen bomb with water but when they're by themselves which they are when you're doing boiling point there's no hydrogen bonding that can take place so high John acceptors only can't hydrogen bond With itself or other molecules of itself where is this 1 right here hydrogen-bond donor plus except and so that 1 has a high school in flickers a convention bold itself so that makes good sense of persons solubility in water 0 per cent for the the infinite for all these guys dipole moment . 5 for the Elkins 2 . 7 I seen different numbers for me is that the the outlined in the Quito similar but they're not exactly the same I think this numbers from your book on Archer are 2 . 7 so similar similar dipole and 1 . 7 the arm alcohol so even tho we have a smaller dipole they'll call has a higher quality for because of hydrogen bomb solubility diminishes rapidly without cartons of just taken we had 1 more carbon onto acetaldehyde here we only over infinite solubility to 20 per cent soluble in water excellent sources say about physical properties of reversible and industry actions about the
heightened he tells that's the main subject of this of this chapter as we saw in Chapter 20 we have strong nuclear files again with the Ukrainian hydride and sodium alkalis once they add to the carbon there on free good they cannot come back off against Somoza irreversible additions on with weaker nucleophile city of water alcohols primary and secondary means and cyanide ion the reaction is reversible so we're going get different products here because of this already start with the really going this order will start with water and retire alcohols and means and cyanide last for all of the regions that Universal Edition we will start with without water through hydration this is what the reaction looks like what she's acetaldehyde here acetaldehyde in the presence of water with tracer Maceda based only traces all you need and if you do that you get this is a new functional group for you this is called a hybrid it's also called a general diet so gentle means that that the 2 alcohols are on the same carbon but more commonly This is the hydrate as were so that's in the functional group that you need to know so it's a carbon this attached to hydroxyl CS no actually there should not be the opposite direction so we actually favor the elder has more stable so this is out of economic conditions and under thermodynamic conditions itself in a very more stable species this is more stable so you again like a little bit of a swarming into very small aso even you know if you think about it even yeah that's odd acetone only have to clean things in the lab that's got a little bit of high-grade varied realize but it does pay so we have to work really hard to get rid of excess acid base you only need trace so unnecessary action the heard that happens to a very small extends to the right if you want actually isolated hydrate you have to drive people of otherwise you will be able to isolate very much all right this is going to have assassin acid in the beast catalyze mechanism so it's get a reminder of reaction from Chapter 9 were reunited Pasadena-based catalyze negatives in that opening up a park sites remember that I made a big deal about that mechanism I put it on the examine reason I made a big deal about is a kind of prepares you well for Cardinal chemistry so a lot of these reactions have an acid catalyzed base-catalyzed mechanism and you need to know brawls and you want avoid common pitfalls missing 10 balls that you have when you did the Parkside of openings so when you have an acid catalyzed mechanism you probably things with an 8 3 0 plus you'll probably things with water because you probably things with water you get hydroxide or if basic catalyze mechanism you probably things with water to produce hydroxide see what it can keep your species separate in acid catalyzed mechanism we don't want to be making negatively charged species in Callas mechanism we don't wanna make Hydro Neumeier has it's not going to be it's going to be present in acid catalyzed mechanism so will do based 1st and so that is trace of hydroxide ceiling catalytic amount and if you can remember what happened with hydroxide and apart site it is directly attacked the Parkside right we did not approach the 1st it's going to be the same thing here so hydroxide irony is going to attack 100 sedentary nuclear power Tuesday attack hydroxide discontent the cardinal directly so great nucleophile the attacks carbonyl directly right so there's going to come from 1 of the lone pairs on to generate attacked the current acquiring kick electrons up on oxygen reversible errors here because I can come right back off again and a lot of the time it does come right back office we wanted to if we want actually isolate hydrated we have to drive equilibrium so it's like that and then we probably here base-catalyzed mechanism we probably it with water and when we do that that's good because now we do that were regenerating our hydroxide catalyst right so check the have made mistakes you that you make sure that you that hydroxide in this last step here we have that and we regenerate hydroxide again attack another Kerviel's so hydroxide attacks directly and then we probably need with water you see why we wouldn't want of from me with an age 3 0 plus here that's a very common mistake on exams to proliferate still plants are we can have a real person base-catalyzed now so that's why you don't want to use that were actually generate hydroxide so that's the base-catalyzed need know the base you also need the acid catalyzed mechanisms so for acid catalyzed Chery serve the aged 3 0 plus presence for the acid Callas mechanism so tinkering member back to a clock sites would we do in the acid catalyzed mechanism we protonated oxygen 1st right where do the same thing here so nice to be able to draw that parallel here we're not approach me with water because if we probably with water we make hydroxide and we'll 1 hydroxide ion appearing in in acid catalyzed mechanisms Oregon approach mate with each 3 plus so there comes from the lone pairs of oxygen we have grab proton and which electrons on oxygen so it's like that that's our 1st step and that's important 1st step because of information makes the carbon you more Elektra Philip we mentioned that now a senior news here probation makes the Carbondale more elective filigreed talk about why in class today and in discussions waiting for elected village so we can nuclear files Water waters are weakening but felt his attack so the base-catalyzed mechanism and about Texas carbon your 1st in acid catalyzed mechanism we probably the oxygen 1st and then the week taxes 2nd so the base-catalyzed reaffirming the 2nd step in nascent because made in the 1st so here's our weak
nucleophile file you know we know that water is a very weak and good flour and so what we need to do is on suit not the electric Felicity Avakov so there we good fucking attack it looks like that so we have a reversible errors all way through here at any point we can reverse back again so this keeps going forward backward forward backward could go up 2 steps backward step and forward Indiana a key goal of 3 steps and back 3 steps his all every single step is reversible if we want to isolate a single product we definitely need to drive the equilibrium all right so now we have only read from the oxygen 1st and all we have been weekly Covell attack last where does some sort of command and I don't what I don't like I don't want you to use the B B-minus Jerry face will what is the actual based here it's water not hydroxide if we use water then we are regenerated catalyst and we don't want use water to program a urgently hydroxide probably because this massacre vise mechanism were not going see hydroxide I need another mechanism in the forward and reverse directions In forward and reverse direction so we're doing the forward direction right now and then discussion were doing the the reversed direction to actually twice and this decision is worksheet for this week question so far anybody right formation of moderate is reversible as we kind of made a big point out of this reversible errors by the way when grading mechanisms on the tests I only great career finally greatest part here I don't whether you have reversible off Orioles you have to worry so much about it but I am trying to show here because of all those steps are definitely reversible doctors of their edition which is formation of a high-grade more stable the company of a less favorable the additional makes sense on the more steric we ended up having a compound the less favored the additions were doing in addition here and so it makes sense that the moral reacted the carbon yielded more hydrate were going to form and if we have a really unstable carbon in the high-grade actually is the favored in some instances so let's compare here we have a acetaldehyde versus Quito we've talked about this already judgment as well as do again there were saying which 1 of these is more like the villain all right so we know that metal is an electron donating groups IRS that's going to donate a little electron density the Internet making it a little bit less positive right so what electron donating makes covariance Poseidon Over here we got to of so that's double the effect isn't so too electron Dominguez make carbon even less positive less positive means more stable so that was our inductive effect is a very slight inducted effect with metal but it's there nonetheless and 2nd thing was on residents affect our Astaire concern effects of this 1 here although is less directly hindered this 1 is more startling hinted that tune-up up of groups more starkly hinted that means it's going to slow down there the rate of beneath the file attacking the so more starkly ended and so what involved in these effects actually work together this what this this compound a key is less subject to nucleophilic attack another way of saying that it is that it's less selective filet right to assistance same so it's also is more stable and since is more stable the hybrid is less so we can completely correlate the hydrate formation the extent of hydrate formation with how stable they on carbon looking at the next example we have we will be able have both have well-defined spent as you can see and when we put fullerenes here we have a pretty dramatic effect here the stories are gonna pull electron density history of I'm so that there are a powerful on the only now we have 3 of them so Silver comparing partial positive charge on the carbonyl carbon which 1 of these guys is going to be more elective the 1st was the 2nd 1 2nd 1 by far so electron withdrawing Florence I think the carbon-carbon were positive therefore it's going to be less stable therefore it's going to be more laughter filler colonies interchangeable ways to Cincinnati more electric more subject to nucleophilic attack more subject to new nucleophilic tariff that more subject to nucleophilic attack than the water's going 1 attack and make a during the period so that means that the hydrates more favor it are rights all different ways to come to the conclusion that the hydrates can more favored do 1 more we're comparing the so I'm very good possibility that you have something where you're comparing the reactivity of carbonyl compounds we already talked about that all mixed in with can have 1 where we have allies and tells with like during periods things like that Our right so we have again we're doing the same thing we're comparing power supplies have charged on the cover new carbon
see which 1 is the most powerful positive charged an ally is seen here is that we do have some resonance stabilization assistance outlined here we do have risen stabilization for events allies so we can draw that resident structure and we can keep going here we can drop onto resonant structures let's do 1 more this is startled by Chapter 18 isn't alright so highly resonant stabilized right so that all by resident stabilized more stable is less reactive so therefore I am less selective feeling we can also say less subject to nucleophilic attack of its sales things and then we can also concluded that the hydrated stimulus favor are executed shot here he did not need to memorize his numbers but you're just wasting some trends here we also remember and this is the equilibrium constant here so that the people constant is greater than 1 that means you actions is favored to the right which forms the hybrid so here's migrate over here and if the equilibrium constants greater than 1 the nitrates favorite so where we stayed for Malahide hydrates favor as a town I about a one-to-one ratio here all of this and this honky-tonk 1 from 1 . 4 times 10 to the minus the so he told his favorite receiver Larry Sanders all coming together here on trade warriors overran the town I'm on now conceivable we always here here's 1 . 0 6 with a 3 4 easily make public to fill again so we also get more hybrid complain of that already here on its favor the show that was less selective Philip more stable so hydrate Tetonia we actually can favor the hybrid will put the 3 forints here and a lot more glorious a better ride for making 108 and sees you definitely see the terms here OK so alarmed that's that's what we're talking about so don't want you memorize those numbers but if I did I find out a bunch aldehydes in Quito's areas you know to rank them or something which one's going to form the most hydrated which means that for the leased the building answer that question just based on understanding that China had questions yes they do and they do but they still contributing structures is not a major thing that the proof is right here and how much hybrid were right so we go from here that 1 . 0 6 and now we go here and it's a tense tenderloins that's really the proof to that is playing a role Over here was another question no OK that's hybrid it people make the the same vaccinations will wear the same sort of statements when we talk about the long edition of alcohols too he tells in our hearts by hammering base catalyzed reaction in acid catalyzed reaction the only difference here is that of the base-catalyzed you get a different product actually than you do the acid catalyzed so this one's a little bit more difficult so here are nuclear file in alcohol so base catalyzed reaction is gonna look a lot like a hydrating moving up just a little then gap better known this is off the topic reversible error also marketed shall we go unanswered then show any particular direction CH 3 0 Linus His are catalysts trace base that's a new functional group we have a common responded to hydroxyl intimate foxy grew bananas called in the acid house so intervention functional groups in this chapter here that's handy acetone a carbon responded well to a hydroxyl and the foxy group Bernal coccyx the mechanism is going to completely remind you of base-catalyzed hydrate formation all right so our nuclear file it is my thoughts I don't know if that's a good news with far-right we're not going to permit the carbon your 1st wooden attack directly so evident that there is going to come from 1 of the long prison not juridical electrons up onto the carbonyl oxygen irreversible steps so I'm having reversible arrows so when we use the base-catalyzed mean we attack the carbon your 1st with the bases and then we probably 2nd everyone approach with methanol so the re re generators with oxide catalyst we don't want approach me with acid that's a very common mistake to promptly with acid here we don't have acid because this is a base catalyzed mechanisms and allow students who are really very prepared for the exam will use a combination of acids and bases in the mechanism using new users don't get any points when you do so you might keep that straight there's a handy answer questions on the base catalyzed mechanism yes because that's where the reactions reversible OK so what happens there never this attack he collected but on oxygen and militants announced down kickoff of boxing that's why we have reversible arose it's going to keep going back and forth but if you want isolating to tell you have to drive people are in business wants to be here what's to be executed by unless it's 1 of those really activated wasn't talked about on the previous page or acid can so what we need is 1st probably the carbon you 1st so far only as intelligent mechanisms that we're going to talk about where appropriate the carbon you 1st with acid there's only 1
exception that of we're having this chapter but in everything else will benefit carbon 1st alright so let me just right up the reaction here 1st and do the mechanism this trio plus origins protonated methanol so you can just add a trace of age to us so far make president methanol here so that would be a catalyst we can formally acetone but typically and the acid tells a difficult to isolate there are some exceptions talk about those coming up but this is this is the Henry acetone generally not Eisele it keeps going and the were to form actually a different product here so happy for him he has to tell all and then this is a versatile so handy half acetate so this 1 has just said there's another new functional group and were not downing of a few more so this an after shall soon after tells the carbonates attested to our secret right on a machine the mechanism for this this is aware of this is a mechanism that 99 per cent of the time I put on the terms it's a very highly likely that you will have this mechanism on the 2 markets say for sure because I was a little bit of freedom here writing the tests but most of the time I do alright so long after scoring economy right here we have a right showing right here and there and I'm so that we do that mechanism in the 2nd column 1st before interest and there we go from the honey as the talked to the acid aren't so this is what it looks like here so as he said as a college mechanism most of the time 98 per cent of China's 1 exception in this chapter but most time carbon your 1st and this is just like what we did in Chapter 9 were reproach the epoxy I 1st same idea there's a reversible errors all the steps reversible at any point in this mechanism we can just go back again it's an equilibrium process the product of this reaction is going to be an nascent talent is is not favored is more stable than Haverty tone than they have in acid tell so we have to drive equilibrium will talk about how you do that all right .period nuclear file is methanol here in the finals a week nuclear violence so we probably need car renewal to make it more elective filets are attack so we can go volatile ,comma we take electrons upon the oxygen so so far looks just like hydration Barcelona we need to do next said they would they with box science right Freedom Party the Parkside 1st the alcohol attacked and probably the alcohol-induced anything here and once we do that we have in the so there's no acetone again generally can't isolate them so it's going to keep going and that's on the next page something to redraw the outstanding as acetone alright so what we need to do here to go unanswered shelters hydroxide ironies to be replaced with them without secret so what's enactment is that his group was going to leave but it's not going to leave as hydroxide why the adults is not of living number 1 and number 2 while we really we had it in the high heightened awareness accounts mechanism we don't want be making hydroxide so we'll probably that 1st so depending on what you have here we can use some you mind if we had had passed we had a catalytic I draw the line on or we did have the needed alcohol which behaves just like petroleum on right both of these have made a few cases the really strong acids focus on inappropriate drops the hydroxyl is what's going away Serbian would have I use exterior posterior continued on other species now there's 2 ways to do this step after this on shave the way I do it share with the book doesn't and you can do it either way doesn't matter to me I like my report of course but you have to my wife OK so the way that I do it is that I have the electrons on this oxygen come down and helped kick off that leaving groups of the kind of push that leaving group right off but you get species here which could looks like a problem carbon it behaves like a Croat leader Cardinal except that we have enough of their instead of a hydrogen on the book shows that we keep going here have been run out of time here but the book shows that this way so I show you shows this way there will keep going well below finishes today that the book shows that this way for that step so once you have this compound here With the program needed alcohol reading them it has that group believes To make a Aqaba Catherine analysts use like this way better and that's perfectly fine and then they have these electrons come down to draw the resident structure I went directly to the resonant structure I will accept both ways both ways are OK both where news of the and we will also that's this step right here that's this step and we will finish this mechanism next time
