Chapter 11, Problem 11A.28E

(a)

Interpretation Introduction

Interpretation:

The optical isomers and the chiral carbons in ${\text{CH}}_{\text{3}}{\text{CHBrCH}}_{\text{2}}\text{Br}$ have to be identified.

Concept Introduction:

Optical isomers:  The compounds that form non-superimposable mirror images of each are called optical isomers.

Chiral molecules:  Optical isomers that occur with four different groups attached to the same carbon atom are called as chiral carbon atom and the molecules are called as chiral molecules.

(b)

Interpretation Introduction

Interpretation:

The optical isomers and the chiral carbons in ${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}{\text{CHClCH}}_{\text{2}}{\text{CH}}_{\text{3}}$ have to be identified.
