Step-by-step solution

Definition of stereoisomers

The stereoisomers are also known as spatial isomers. These are the kind of isomers with similar molecular formulas and also the same sequence of bonds.

The stereoisomers differ from each other only in the three-dimensional positionings of their atoms. They are further classified as enantiomers and diastereomers.
