Question

Based on the reaction given above, choose the correct options:

• A. The products are stereoisomers
• B. The products are constitutional isomers
• C. The reaction proceeds via electrophilic aromatic substitution
• D. The mechanism involves a benzyne intermediate

Answer 1

Answer: (B), (D)

The correct options are
B The products are constitutional isomers
D The mechanism involves a benzyne intermediate

The given reaction is a type of aromatic nucleophilic substitution reaction which proceeds via benzyne mechanism due to involvement of benzyne intermediate.
The products formed are constitutional isomer having same molecular formula with different bonding pattern.
