This question asks us why we only get one product from doing hydroboration oxidation on two butine, but we get two products when we do it on two pentine.
00:18
So look at the symmetry of these molecules.
00:21
With two butyne, if we draw a line straight down the middle, we have two carbons on each side.
00:26
It's a symmetrical alkyne.
00:29
So whether we put the oh on this carbon or on this carbon, once we, to tamerize that, it's going to be carbon too no matter what.
00:36
It's always going to be the same.
00:38
But on two pentine, this is carbon two, this is carbon three, and no matter, you know, we can put it on both.
00:46
So if we put it on carbon two, then we'll have a ketone on carbon two...
