In this problem, we're looking at the relationship between two given structures.
00:05
So we have one that shows an alcohol group in front of the plane.
00:12
And then we have one that shows it behind the plane.
00:17
So notice that our carbons here and here are chiral.
00:23
So there's four different groups.
00:26
So here there's a hydrogen we didn't draw in.
00:29
And the same thing here.
00:31
Now, to determine our relationship, we're going to have the first.
00:33
Find our stereo center.
00:37
So that's going to be either r or s.
00:41
So to start, we look at the heaviest atom coming off of our red carbon.
00:45
And that's going to be oxygen...
