Question

The final product A, formed in the following multistep reaction sequence is:

• A.

  

• B.

  

• C.

  

• D.

  

Answer 1

The Correct Option is A

Step 1: Bromobenzene reacts with Mg in ether to yield the Grignard reagent, phenylmagnesium bromide.

Step 2: Carbon dioxide reacts with the Grignard reagent, followed by acidic workup, to produce benzoic acid.

Step 3: Benzoic acid undergoes a Hoffmann bromamide reaction, converting the amide to an amine, thus forming aniline.

The final product is aniline (structure in option (1)).
