Chapter 4, Problem 64P

Interpretation Introduction

Interpretation:

The reason should be explained for the given compound has four stereoisomers when it has only one asymmetric center.

Concept introduction:

The total number of stereoisomers can be calculated by using following formula,

$\begin{array}{l}\text{The total number of stereoisomers}\text{=}{\text{2}}^{\text{n}}\\ \text{n}\text{=}\text{number}\text{of}\text{chiral}\text{carbon}\end{array}$

Cis–trans isomerism (or) geometric isomerism or configurational isomerism:

The two similar groups (or higher priority groups) are in same side in double bond of alkenes is called as cis isomer (or Z-isomer). Two similar groups (or higher priority groups) are opposite side in double bond of alkenes is called as trans isomer (or E-isomer).

Example:
