Chapter 10.6, Problem 12E

Interpretation Introduction

Interpretation:The class of mechanism that can be suggested for bromide ion attack on cyclic bromonium ionformed during the formation of $\text{meso-stilbene}$ dibromideshould be written.

Concept introduction:Alkenes are considered electron-rich and undergo bromination addition reaction with ${\text{Br}}_2$ in presence of ${\text{CCl}}_{\text{4}}$ by electrophilic addition reaction.

The $\text{meso-stilbene}$ dibromide product can only be formed if this $\left(\text{E}\right)\text{-stilbene}$ acts as the substrate in this specific stereochemistry indicated in the mechanistic pathway below.
