Interpretation Introduction

Interpretation:

The reactivity of the following compound –

                   

Towards bromination has to be predicted.

Concept Introduction:

Bromination of aromatic compounds is the phenomenon of inserting $\text{-Br}$ group on aromatic ring. The pi electrons of the aromatic system must be available freely for this to occur. Further, the aromatic ring must not have many bulk substituents on it to ease the any type of electrophilic substitution reaction. Presence of many bulk substituents hinders the ability of the delocalizing pi electrons to bond with the electrophile.
