WebApr 6, 2024 · In methylcyclohexane, for example, there are two conformational isomers, one with the methyl group axial and one with the methyl group equatorial. The two interconvert through ring flipping. Which isomer is more stable? For the axial methyl isomer the methyl group interacts unfavourably with nearby methylene groups. WebThe stereoisomeric 1,2-dibromocyclopentanes shown to the right are an example. In general, if any two sp 3 carbons in a ring have two different substituent groups (not counting other ring atoms) stereoisomerism is possible.
