Hi there.
00:05
We are talking about mirror image isomers, and we want to know what does molecule have to look like to give us a mirror image isomer.
00:16
And the answer to that is that the central atom, typically it's a carbon, needs to have four different things attached to it, four different groups.
00:28
Let's look at what we mean there.
00:31
So here's our central atom.
00:32
I'm going to make this one a carbon atom here.
00:35
And then i'm going to attach four different groups to it.
00:40
So i'm going to give it a tetrahedral shape because carbon with four things attached to it gives us a tetrahedral shape molecule.
00:50
Right.
00:51
So one of these is going to just be my open circle there.
00:58
I will make another one of these red.
01:05
I'll make one of these green and one of these blue.
01:17
Then i'm going to stick a mirror in the middle here.
01:20
I'm going to sketch the mirror image of this.
01:25
So here's the carbon in the middle.
01:32
Here is that one.
01:33
So far so good.
01:35
It can superimpose upon itself so far, meaning that we could stack it on top of it.
01:41
It will be identical...
