So we have two different organic molecules.
00:03
We have molecule a, which is serine, and molecule b, which is adrenaline.
00:08
And the question asks us to assign configuration to the chiral centers of each of these molecules.
00:14
So looking at serene, we can go ahead and assign configuration based on our priorities.
00:19
So assigning priority, we see that our nitrogen is going to be the highest mass compared to our carbons and hydrogens.
00:28
So that's going to receive priority number one.
00:30
And now looking at the carbicsilic acid versus the ethanol, we see that our carbicilic acid here is going to have the higher priority because our carbon is going to be, it's going to share three bonds with the two oxygens, whereas our ethanol carbon is going to share one bond to the oxygen and two bonds to two different hydrogens.
00:51
And so ethanol will be number three.
00:53
And then our hydrogen, of course, is number four.
00:56
So here, looks at least.
00:58
Like we're going clockwise, which we would normally say is r...
