So this comes from chapter four, question eight, visual skills, which of the molecules shown in question five has an asymmetric carbon? which carbon is asymmetric? so here are the two molecules, molecule one and molecule two from question number five.
00:20
And remember, you can know which carbon is asymmetric based on which carbon has a different, has four.
00:31
Different side chains, right? so it's not just what atoms isn't bound to, but what side chains are different.
00:44
So for instance, this carbon here has two of the exact same side chains, right? so this carbon is bound to two hydrogens, one hydroxide.
00:57
This carbon is bound to a hydroxide and two hydrogens.
01:00
So these two are actually going to be the same side chain.
01:08
But that doesn't matter because you need to have four different side chains, and this carbon clearly only has three side chains in total, two of which are different.
01:21
So you've got this kind and this bond to an o.
01:29
But anyways, let's go through and try to find the asimam.
01:33
Carbon.
01:34
So this carbon here has two hydrogens.
01:37
Those are the same.
01:38
So here's one type of bond, a bond to hydrogens, a bond to hydroxide.
01:47
That's a second kind, and then a bond to this r group.
01:52
So that's a total of three different side chains and this carbon right here.
01:59
And this carbon, again, we've got two different types of side chains...
