Chapter 12.10, Problem 11P

Interpretation Introduction

Interpretation:

The product formed from the reaction of $\text{N-bromosuccinimide}$ with each of the given starting materials is to be identified.

Concept Introduction:

>

Benzylic carbons are those which are directly attached to the benzene ring.

>

The hydrogen atoms attached to benzylic carbons are called benzylic hydrogens.

>

The benzylic hydrogen is preferably abstracted during substitution in the free radical halogenation of alkyl benzene.

>

Using $\text{N-bromosuccinimide}$, the benzylic hydrogen is selectively substituted by bromine.
