Which from following is a non benzenoid aromatic compound?

Step-by-step solution

Non-benzenoid aromatic compounds satisfy Hückel's rule while lacking a benzene ring structure. Aniline contains a benzene ring, making it benzenoid aromatic. Naphthalene consists of fused benzene rings, classifying it as benzenoid aromatic. Phenol features a benzene ring substituent, rendering it benzenoid aromatic. Tropone forms a seven-membered cycloheptatrienone ring with 6 electrons satisfying Hückel's rule ( 4n + 2 where n = 1 ), establishing it as non-benzenoid aromatic. The non-benzenoid aromatic compound is
