Okay, this problem is asking us which of these compounds represents a cis isomer.
00:04
So a cis isomer is basically a, in this case, a cyclohexene that has substituents on the same side.
00:10
So i'm going to have them either both up or both down.
00:12
Okay, so let's analyze this first one.
00:14
So that first one, i have this methyl group right here that is pointing straight up.
00:19
Okay, so that is going to represent up.
00:21
And then i have this other methyl group pointing straight down.
00:24
So these are both considered to be in the axial position.
00:26
This one is pointing up.
00:27
This one is pointing down.
00:28
Those are on opposite sides, right? because we have one up, one down.
00:31
So that is trans, that is not cis.
00:34
Okay, what about this one? so this one, we have two equatorial positions of those two metals, sorry, those two methyl groups...
