Question

Among the given compounds I-III, the correct order of bond dissociation energy of the C-H bond marked with is:

• A. I $>$ II $>$ III
• B. III $>$ II $>$ I
• C. II $>$ I $>$ III
• D. I $>$ III $>$ II

Hint:

Resonance stabilization (like in aromatic compounds) usually increases the bond dissociation energy, while strain (like in cyclopropanes) decreases it.
