Vedclass · Answer

(B) To determine aromaticity,we use $H$ückel's rule ($4n+2$ $\pi$ electrons,planar,cyclic,conjugated):$A$. Heptafulvene: It is non-aromatic because it is not fully conjugated in a way that satisfies the $4n+2$ rule for the entire ring system.$B$. Benzene: It is aromatic ($6$ $\pi$ electrons,$n=1$,planar,cyclic,fully conjugated).$C$. Cyclopentadienyl anion: It is aromatic ($6$ $\pi$ electrons,$n=1$,planar,cyclic,fully conjugated).$D$. Cyclopentadienyl cation: It is anti-aromatic ($4$ $\pi$ electrons,$n=1$,planar,cyclic,fully conjugated).Therefore,compounds $B$ and $C$ are aromatic.

Among the following,the aromatic compounds are:
$(A)$ Heptafulvene
$(B)$ Benzene
$(C)$ Cyclopentadienyl anion
$(D)$ Cyclopentadienyl cation
