Chapter 25, Problem 31QP

Interpretation Introduction

Interpretation:

Thestatement “alkenes exhibit geometrical isomerism because rotation about $\text{C=C}$ is restricted”is to be explained.

Concept introduction:

Isomers are those molecules thathave the same molecular formula but different arrangement of atoms.

Geometrical isomerism is commonly known as cis–trans isomerism. These are isomers having the same type of atoms but which differ in the geometric structure.
