Question

The major product of the following reaction is 

• A.

  

• B.

  

• C.

  

• D.

  

Hint:

For the halogenation of aromatic compounds in the presence of electrophilic substitution, the halogen attaches to the ring at the position that provides the most stable intermediate, usually the position ortho or para to the substituent.

Answer 1

The Correct Option is A

Step 1: The reaction involves the halogenation of the aromatic ring in the presence of bromine (\( \text{Br}_2 \)). This leads to the substitution of a hydrogen atom by a bromine atom in the ring, producing the brominated product. The correct product is the one where the bromine attaches to the phenyl ring in the presence of the carboxylic acid group, forming \(\text{C}_6 \text{H}_4 \text{COOH} \text{Br}\). Thus, the major product is \(\text{C}_6 \text{H}_4 \text{COOH} \text{Br}\).
