So here we have three types of isomers drawn out.
00:02
The first is a constitutional isomer.
00:05
And you know that two things are constitutional isomers because their connectivity is different.
00:10
So for example, i'm going to draw two molecules that have four carbons, right? so this right here is one.
00:20
And both of those have the same number of carbons, but you can tell they're very different molecules.
00:26
So a geometric isomer means that the connectivity of the atoms is the same, but their orientation with respect to a very rigid point is different.
00:41
So what that means is, say, i have a double bond or a ring.
00:45
A geometric isomer is going to be the have the same connectivity, but instead be oriented about that double bond or that ring differently.
00:54
So for example, let's say i had a double bond here...
