Question:

X and Y in reactions:

Show Hint

Use Fe/Br$_2$ for aromatic substitution, hv/Br$_2$ for side-chain bromination.
Updated On: Oct 27, 2025
  • X: Br$_2$/Fe; Y: Br$_2$/hv
  • X: Br$_2$/CH$_3$COOH; Y: Br$_2$/CH$_3$COOH
  • X: Br$_2$/CH$_3$COOH; Y: Br$_2$/Fe
  • X: Br$_2$/Fe; Y: Br$_2$/CH$_3$COOH

The Correct Option is A

Solution and Explanation

Electrophilic aromatic substitution on benzoic acid gives meta-bromination with Br$_2$/Fe. Side-chain bromination occurs under radical conditions (hv).
