WebSep 24, 2024 · Cis and trans stereoisomers of 1,3-dimethylcyclohexane A similar conformational analysis can be made for the cis and trans stereoisomers of 1,3-dimethylcyclohexane. For cis -1,3-dimethylcyclohexane one chair conformation has both methyl groups in axial positions creating 1,3-diaxial interactions. WebIn fact, 1,3-dimethylcyclopentane has only 2 chiral centres and 3 distinct stereoisomers. Try drawing the molecule out with the two methyl groups trans to one another (both up), you will then notice that there is a centre of symmetry - This "trans" form is a mess compound.
