Chapter 4, Problem 62P

(a)

Interpretation Introduction

Interpretation:

The given pairs of compound identical, enantiomers, diastereomers, or constitutional isomers have to be drawn.

Concept introduction:

Isomer: A molecule having the same molecular formula but with different chemical structure is called isomer.

Stereoisomers: Stereoisomers are molecules that have the same molecular formula and they differ only in arrangement of atom in three-dimensional space.

Enantiomers: A compound which is non-superimposable mirror image is called enantiomers.

Diastereomers: A compound which is non-superimposable and non-mirror image is called diastereomers.

Constitutional Isomers: A molecule having same molecular formula with different structural formulas (Difference in the connectivity of the molecule is called constitutional isomer).
