2. Please consider the two all 'cis' isomers of trimethylcyclohexane drawn below. Draw the two chair conformers of each stereoisomer below (1 and 2) and calculate their torsional interaction energies in order to identify the lower energy conformer for each stereoisomer. Based on your calculations, state which of the two stereoisomers 1 and 2 is less stable and which is more stable. [1,3-diaxial CH3 CH3 = 3.7kcal/mol; 1,3-diaxial CH3 H = 0.88kcal/mol; cis-1,2 (axial:equatorial) CH3 CH3 = 0.88kcal/mol; trans-1,2-diequatorial CH3 CH3 = 0.88kcal/mol) all-cis-1,2,3- 1 all-cis-1,2,4- 2
