When you go around the ring, you stop at the first point of difference. The groups directly attached to C-3 in 3-chlorocyclohexene are H, Cl, CH₂, and CH. You can stop there, because these are four different groups. If you go one atom further, the groups are H, Cl, CH₂-CH₂, and CH=CH.

WebThe atoms attached to C5 are C, H, H. There is no difference. To decide between C2 and C5, we must go one atom further out. From C2, C3 has F, C, H. From C5, C4 has C, H, H.
