Question

The major products formed:

A and B respectively are:

• A.
• B.
• C.
• D.

Answer 1

Answer: (B)

Answer 2

The reaction proceeds as follows: 1. The anisole (methoxybenzene) undergoes nitration with $\text{HNO}_3/\text{H}_2\text{SO}_4$ to form the product (A), which is 4-nitroanisole. 2. Subsequently, bromination with $\text{Br}_2$ (in the presence of excess iron) results in the brominated product (B), 4-bromo-2-nitroanisole.

Thus, the major products are (A) and (B) as represented in option (2).
