WebThe trans-1,3-dimethylcyclohexane isomer , on the other hand, has one methyl axial in both ring-flip conformers, so that it is less stable than the cis isomer by 1.8 kcal/mol. Both trans-1,4-dimethylcyclohexane and cis-1,3-dimethylcyclohexane have essentially the same energy, since neither one of them has any strain at all. WebSep 22, 2016 · Now, imagine what the cis and trans isomers would look like for 1,3-dimethylcyclobutane. In the cis isomer both $\ce{H'}$ on $\ce{C-1}$ and $\ce{C-3}$ would be replaced by $\ce{-CH3}$ groups (since they are on the same side). Of course there will be considerable repulsions if they are arranged in the conformation on the left, which is …
