The stable conformer `(s)` of trans`-1-4-` dimethyl] cyclohexane is/are:

The stable form of trans-1,4-dimethylcylohexane is represented as:

Each Me/H, 1,3-diaxial interaction imparts 3.75 kJ mol^(-1) and each Me/Me, 1,3-diaxial interation imparts 15 kJ mol^(-1) of instability to a compound. Find the energy differences between the more stable conformers of a. Cis - and trans-1,3-dimethyl cyclohexane. b. (e,e) and (a,a) trans-1,2-dimethyl cyclohexane. c. cis- and trans-1,1,3,5-tetramethyl cyclohexane.

The most stable from trans-1,2-dimethyl cyclohexane is:

The most stable conformational isomer of trans-1-ethyl-2-methylcyclohexane will be

The most stable confomation of cis-1,4-di-t-buty1 cyclohexane is:

The stable conformer (s) of cis-cyclohexane 1-3- diol is/are:

Equal amounts of (e, e) and (a, a) conformers of trans-1,2-dichloro cyclohexane exist in non-polar solvents but the (e, e) conformer exists in polar solvents. Explain.
