Chapter 5, Problem 5.14P

Interpretation Introduction

(a)

Interpretation:

Whether the given molecule is chiral or achiral is to be determined.

Concept introduction:

If a molecule is superimposable on its mirror image, it is achiral. If the molecule possesses a plane of symmetry, then it will bisect the molecule into two equal half parts, making the molecule achiral. In the chair conformation of disubstituted cyclohexane, if the two substituents are identical, the relative positioning of the substituents with respect to the plane of the ring determines if a plane of symmetry can exist.
