So the reason for this is really just comes down to geometry.
00:06
So cyclohexene, if you look at this normal drawing here, all right, this is cis.
00:15
It's a hexagon.
00:16
All the angles are around 120 degrees.
00:18
All right, the carbons are happy.
00:22
If we try to draw it trans here, one, two, three, four.
00:28
We have two carbons left to put this ring back together.
00:32
And there, you know, we could try to put them here, that.
00:36
And it just doesn't work.
00:39
Okay.
00:41
This is extremely unfavorable...
