For cis -13-dimethylcyclohexane one chair conformation has both methyl groups in axial positions creating 13-diaxial interactions. The conformation in which the both the methyl groups are on the equatorial position will be more stable conformation of the cis-stereoisomer. Thus D and E chair conformations are in equilibrium.
A Indicate by a label whether each methyl group is axial or equatorial. There are two possibilities that are cis or trans but the position of the methyl group on axial or equatorial bond on cyclohexane determines whether the compound is cis or trans. A B C D E F.
The diaxial form would be more than 2 x 18 kcalmol because the two methyl groups would run into each other rather than just into an axial hydrogen. Like in given figure no. Yet even though each conformation has two asymmetric carbons neither conformation is chi-ral because each has an internal plane of symmetry.
