Chapter 12, Problem 86P

Interpretation Introduction

(a)

Interpretation:

A cycloalkene gives following compound on reaction with ${\text{Cl}}_{\text{2}}$.Deduce the structure of the alkene.

Concept Introduction:

The addition of ${\text{Cl}}_{\text{2}}$ on alkene is an electrophilic addition, where the chlorine molecule is being attacked by pi bond and forms a cyclic halonium ion as intermediate, this is further attacked by chloride ion to give dichloroalkane.
