From studies of the dipole moment of 1,2-dichloroethane in the gas phase at room temperature (25°C), it is estimated that the ratio of molecules in the anti conformation to gauche conformation is 7.6 to 1. Calculate the difference in Gibbs free energy between these two conformations.
When cyclohexane is substituted by an ethynyl group, -C=CH, the energy difference
between axial and equatorial conformations is only 1.7 kJ (0.41 kcal)/mol. Compare the
conformational equilibrium for methylcyclohexane with that for ethynylcyclohexane and
account for the difference between the two.
sketch the various conformational isomers of 1,3-dimethylcyclohexane. Indicate the position (axial/equatorial) of each of the methyl groups in each structure.
