Suppose we have the product of either 3s4s for bromo 3 hexanol or 3r4r for bromo 3 hexanol.
00:15
And what that means is either we have 2s's, which would be 1, 2, 3 goes counterclockwise.
00:30
So that would be an s.
00:33
And we have one, two, three, also an s, or we have them as dashes.
00:49
So we want to make the same stereo center.
00:53
But we are reacting it with br2 in water.
00:58
And this follows the same mechanism as, well, br2, in the sense that it's anti -edition.
01:06
So how will we make that? how will we make the same stereo center if we have an anti -addition of an alken, or onto an alken, how would we get the same stereo centers? how would we get the same stereochemistry? well, what we can do is these are both alkanes, right? we can agree that these are both alkanes.
01:31
There's a freedom of rotation in alkanes...
