In this problem, we start with this alkyne here.
00:04
We undergo a series of reactions, and we're asked for our final product.
00:10
So our first step, we're looking at the reagents for hydroboration oxidation.
00:16
So this will add a hydrogen and an alcohol across our double bond.
00:20
And this is called an anti -marcovnikov addition, meaning our least substitute carbon, this one here, we did our alcohol.
00:28
And this is less substituted because it's attached to two carbons, whereas this one is attached to three.
00:36
So over here, we'll get a product like this.
00:40
And this next step, you have to be careful.
00:44
This isn't going to be a substitution reaction.
00:46
And you can remember alcohols are really bad leaving groups...
