False

8. What is the relation between the given compound?

diastereomers

identical

enantiomers

constitutional isomers

9. Which of the following statements most accurately describes the stereochemistry between the various cyclohexanes?

The conformational isomers of trans-1,2-dichlorocyclohexane are enantiomers, which are not interconvertible, but resolvable

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

The diaxial and diequatorial forms of trans-1,3-dichlorohexane can be separated by their differing physical properties

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

10. Is the given pair of compound enantiomers?

True

False
