Chapter 11, Problem 36P

Interpretation Introduction

Interpretation:

The reasonable structures for the two isomers produced in the bromination of $\text{1,5-cyclooctadiene}$ with $\text{N-bromosuccinimide (NBS)}$ are to be determined.

Concept Introduction:

>

The allyl group contains the unit ${\text{CH=CH-CH}}_{\text{2}}$ .

>

The atoms or groups attached to the allylic carbon atoms are the allylic substituents.

>

Allylic carbocations can be stabilized by electron delocalization.

>

Allylic bromination is normally carried out using $\text{N-bromosuccinimide}$.
