Question

how do you convert benzene to 4 bromonitrobenzene

Answer 1

Benzene to P - bromo nitro benzene.

Answer 2

Answer:

Benzene can be converted into 4 Bromonitrobenzene by following the steps below:

i) Bromination: Heat Benzene with Br2 in the presence of Anhydrous $\mathrm{FeBr}_{3}$.

ii) We will obtain bromobenzene as the product of the first step. Perform nitration of bromobenzene in the presence of concentrated $\mathrm{HNO}_{3}$ and concentrated $\mathrm{H}_{2} \mathrm{SO}_{4}$. After this step, you will obtain orthobromonitrobenzene as the minor product and parabromonitrobenzene as the major product. We can perform the fractional distillation to get pure parabromonitrobenzene.
