Which of the following statements most accurately describes the stereochemistry between the various cyclohexanes? |
A. | Cis-1,2-dichlorocyclohexane and trans-1,2-dichlorocyclohexane rotate plane-polarized light in opposite directions, and together in equal proportions form a racemic mixture |
B. | The diaxial and diequatorial forms of trans-1,3-dichlorohexane can be separated by their differing physical properties |
C. | Only cis-1,4-dichlorocyclohexane is achiral due to a plane of symmetry, and cis-1,4-dichlorocyclohexane is diastereomeric to trans-1,4-dichlorocyclohexane |
