"WebThe trans -1,2-dimethylcyclohexane has two energetically non-equivalent conformers. Due to the absence of 1,3-diaxial interactions, the diequatorial form is more stable and abundant than the diaxial conformer. In contrast, both conformers of the cis- isomer have equivalent energies with one axial and one equatorial methyl group. " - Cis vs trans cycloalkanes
