 Okay, let's do this last problem. I think I'll only have enough battery life for one more anyway So and I'll post all the videos right after this. So It's this one here. So Yeah, so we're gonna make a tertiary alcohol as you can see So this is the same mechanism I was making a tertiary alcohol from an acid chloride Asters and acid chlorides are effectively the same thing. Don't worry about it Is it bleak thing? Oh So acid acids and acid chlorides are effectively the same thing But acid chlorides are more reactive Okay, same thing as in if you want to use them as a starting material to make something else Okay, but as chlorides are more reactive. So they tend to be used more, you know But esters are easier to get so you don't have to make the acid chloride from the carboxylic acid So anyways So the first step of course is like me that just stood for methanol. So we've got the ET Mgvr, so Remember this is essentially carbamide, right? So it's going to attack That carbonyl carbon So it's going from sp2 to sp3 intermediate Intermediate of course is going to be have stereochemistry, but it's going to break back down So we don't have to worry about it. So that's the newly added apple group there Like that. Okay, so this is your intermediate. Same intermediate that you keep seeing What's going to happen now though is you've got this good leading group Okay, so this is going to break back down and knock that out So in fact what you get is an intermediate from this is a ketone just like In the acid chloride mechanism. Okay, so that's your ketone You're going to have of course the methoxide the Mgvr It's going to be associated with it But remember we have excess of this stuff. Okay, so what's going to happen now? Is you're going to have another one ketone is less reactive but still reactive enough to Have a greener reagent react with it so So again greener reagents you want to make sure everything's got negative charges no positive charges when you're dealing with a greener solution because It makes the solution very basic. Okay, we've talked about that before like acidic solutions Always positive and neutral basic solutions always negative and neutral. Okay, so no positive charges until Right now right in the second step Well in the second step, you just add water So in fact, there's not even gonna be a positive Yeah, that's already washed away Yeah, because you're putting a bunch of water in there, but if you want to You can that balance your charges Yeah, no, yeah, it's good to take account of everything, you know, and and you're right in Organic chemistry, you know organic chemists usually kind of just discount that you know what I'm saying because of the way You know, we think we think about the reaction happening We're like, oh that thing's already gone because we washed it out. You know what I'm saying things like that So, but yeah, it's good to kind of keep track of every atom, especially when you're in that in your situation where you're like I'm not sure if I've Actually broken this bond and what piece came off and things like that So if you have trouble doing that which most introductory organic students do, you know Just keep account of everything, you know, don't buy kind of brush over steps like I do, you know what I'm saying We cool
