Okay, this problem is asking us to predict the product of this reaction.
00:04
So first up, we have an aldehyde, right? this might be a little bit confusing because we don't have that hydrogen shown, but we can just go ahead and write that out for ourselves.
00:10
Right, so this is my aldehyde, and then this is my alcohol.
00:13
So in the reaction between an aldehyde and an alcohol, what product are we going to get? right? so it only specifies that we have one equivalent of this alcohol.
00:21
If we had two equivalents, then we might expect to form an acetyl.
00:26
But if we only have the one equivalent, that is the point that we understand that we have to form a hemisotel, which is just one alcohol added.
00:33
So in the mechanism, i'm going to go ahead and add this alcohol to this carbonyl, right? because my carbonyl is considered electrophilic, my alcohol is considered nucleophilic.
00:42
I can go ahead and add these electrons to this carbon, right? because that is the electrophilic carbon.
00:47
But as i add those electrons to that carbon, i have to move these electrons up to this oxygen.
00:51
So as i do that, i will form this product in which i have my oxygen with a negative charge.
00:56
I have my single bond to this carbon.
00:59
So this carbon was the one that was attacked.
01:01
And attached to that carbon, we have my methyl group, so ch3...
