Step-by-step solution

Enantiomers and Diastereomers

Enantiomers represent a compound pair where one compound is the mirror image of another compound. In the case of a diastereomer pair, one specific compound and its pair cannot be a mirror image.

Enantiomers and Diastereomers of compounds a, b, and c

a. Enantiomers are pair of compounds that possess non-superimposable mirror images. In the compound is drawn below, hydroxyl group and hydrogen group are found above and below the plane.

Diastereomers are pairs of compounds that are neither superimposable nor mirror images of each other.

The enantiomers and diastereomers of compound a are given below:

b. In the given compound, the hydrogen group and the iodide group are present above the plane in a particular compound. The mirror image of the compound will possess both the groups located below the plane.

The enantiomers and diastereomers of compound b are given below:

Enantiomers and diastereomers of compound b

c. In the compound mentioned below, the hydroxyl group and amino group are situated above the plane. In the mirror image, both these groups are situated below the plane.

In the case of diastereomer, the hydroxyl group is placed below the plane, and the amine group is present above the plane.

The enantiomers and diastereomers of compound c are given below
