Consider both chair conformations for cis-1, 4-dimethyl-cyclohexane and thus select the correct statement : Select one: a. Both Methyl groups in the equatorial positions (positions 184) is the more stable possible conformer b. Both Methyl groups in the axial positions (positions 184) is the more stable possible conformer c. Both possible conformers for this di-substituted derivative are of equal stability d. The conformer with both methyl groups (positions 184) not showing any 1, 3diaxial repulsion is the more stable possible conformer
