For cis -1,3-dimethylcyclohexane one chair conformation has both methyl groups in axial positions creating 1,3-diaxial interactions. WebStep-by-step explanation. Detailed explanation: 1) The chemical formula for ethene is C2H4. H ─ C = C ─ H. We add a methyl group in place of a hydrogen atom on each of the two carbons to get 2-butene, C4H10 (-CH3). To make the cis and trans stereoisomers, we can link the methyl groups in one of two methods. Cis-2-butene's structural formula ...
