Identify the compound, which has maximum number of no bond resonance structures.
Identify the compound, which has maximum number of no bond resonance structures.
Solution
Key Idea More be the H-atoms associated (bonded) with the $\mathrm{C}$-atom, which is bonded with the benzene ring, more will be the number of 'no bond resonance' structures shown by them.
the ring has $3 \mathrm{H}$-atoms.
Hence, option (d) is the correct answer.
