Vedclass · Answer

(C) species is aromatic if it is cyclic, planar, fully conjugated, and follows $H$ückel's rule $(4n+2) \pi$ electrons. $1$. $p$-Benzoquinone: Non-aromatic (contains $sp^3$ hybridized carbonyl carbons).$2$. Cycloheptatrienyl cation: Aromatic ($6\pi$ electrons, cyclic, planar, fully conjugated).$3$. Phenanthrene: Aromatic ($14\pi$ electrons, cyclic, planar, fully conjugated).$4$. $1,4-$Cyclohexadiene: Non-aromatic (contains $sp^3$ hybridized carbons).$5$. Cyclobutadiene dication: Aromatic ($2\pi$ electrons, cyclic, planar, fully conjugated).$6$. Cyclohexadienyl anion: Non-aromatic (contains $sp^3$ hybridized carbon).Thus, the aromatic species are: Cycloheptatrienyl cation, Phenanthrene, and Cyclobutadiene dication. Total count = $3$.

The total number of aromatic compounds/species from the following is:
