Chapter 5, Problem 5.1YT

Interpretation Introduction

Interpretation:

Using a molecular modeling kit, the molecule shown on the right in Figure 5-2a is to be oriented so that the C, Br, and F atoms occupy the positions shown in the second structure. The drawing of the molecule is to be completed by adding H and Cl atoms in the positions where they appear in the molecular model. Then, these two structures are to be compared to see if they are superimposable.

Concept introduction:

Enantiomers are mirror images of each other. To be isomers of each other, however, they must be different in some way. Enantiomers, therefore, are nonsuperimposable mirror images. Molecules are nonsuperimposable if there is no orientation in which all atoms of both molecules can be lined up perfectly (i.e., superimposed).
