Question

Chapter 5, Problem 5.79P

Interpretation Introduction

(a)

Interpretation:

It is to be shown that the given molecule does not have a plane of symmetry.

Concept introduction:

A plane of symmetry is an internal mirror plane that divides the molecule into two halves that are superimposable mirror images of each other.

Interpretation Introduction

(b)

Interpretation:

The molecule’s mirror image is to be drawn. It is to be shown that the molecule and its mirror image are superimposable.

Concept introduction:

A molecule’s mirror image is obtained by reflecting every atom through a mirror plane. The mirror image can be rotated through different axes to see if the molecule and its mirror image are superimposable.

Interpretation Introduction

(c)

Interpretation:

The location of the point of symmetry of the molecule is to be identified.

Concept introduction:

For each atom in the molecule, if there is an identical atom at an equal distance across the center of the molecule, the central point is called the point of symmetry.
