(a)

Interpretation Introduction

To determine: The stereochemical relationships between each pair of structures and the process of separation of these structures by distillation or recrystallization.

Interpretation: The stereochemical relationships between each pair of structures are to be identified and the process of separation of these structures is to be stated.

Concept introduction: If two compounds have same molecular formula, but the spatial arrangement of atoms is different, then they are known as stereoisomers. Stereoisomers are further divided into two categories: optical isomers and geometrical isomers. The two different forms in which a single chiral carbon can exist is referred as enantiomers. The class of diastereomers includes stereoisomers that are not enantiomers. They are not the mirror images of each other. There are two or more chiral centers generally present in diastereoisomers.
