Vedclass · Answer

(B) Aromatic compounds are classified into two types: benzenoid and non-benzenoid. Benzenoid compounds contain at least one benzene ring, such as $Aniline$, $Naphthalene$, and $Phenol$. Non-benzenoid aromatic compounds possess aromaticity but do not contain a benzene ring. $Tropone$ (cycloheptatrienone) is a classic example of a non-benzenoid aromatic compound because it follows Hückel's rule ($4n+2$ $\pi$ electrons) and has a cyclic, planar, conjugated structure without a benzene ring.

Which of the following is a non-benzenoid aromatic compound?
