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 |
