D

Text Solution

Verified by Experts

The correct Answer is:
4
`-CN` group is converted into `-COOH` group under given reaction since `-COOH` group is at `C_(2)` that means one of the chlorine atom is present at `C_(2)` carbon and always when two `-COOH` group are at same carbon atom subsequent heating loses `CO_(2)` so both chlorine atoms are at same `C_(2)` position.
