Chapter 5, Problem 5.18P

Interpretation Introduction

Interpretation:

From the molecules shown in Figure 5-19, the enantiomers and diastereomers of molecule A are to be determined.

Concept introduction:

When the configuration is reversed at all the chiral centers, then they are said to be enantiomers. When the configurations at some but not all chiral centers are reversed, the molecules are diastereomers.

The configuration at a chiral center is reversed when the positions of two of the four attached groups are exchanged.
