(a) Interpretation: The structure of an achiral tetramethylcyclohexane for which the chair interconversion results in identical molecules is to be predicted. Concept introduction: Conformation isomers are formed by the rotation about single bond while the atoms and connectivity remains same. For cyclohexane, the most stable conformation is chair conformation in which all the carbon-hydrogen bonds are staggered. Axial bonds are above or below the plane of the ring while equatorial bonds are in the plane of the ring.
