Vedclass · Answer

(D) Aromatic compounds are highly stable due to the delocalization of $\pi$ electrons over the entire ring. For a molecule to be aromatic,it must follow $H$ückel's rule,having $(4n+2) \pi$ electrons in a planar,fully conjugated system.$A)$ Benzene is aromatic ($6 \pi$ electrons).$B)$ Furan is aromatic ($6 \pi$ electrons,including the lone pair on oxygen).$C)$ Pyridine is aromatic ($6 \pi$ electrons).$D)$ $4,4-$dimethylcyclohexa$-2,5-$dien$-1-$one has an $sp^3$ hybridized carbon at the $4$-position,which breaks the continuous conjugation of the ring. Therefore,it is non-aromatic and shows the least resonance stabilization compared to the other aromatic options.
