Vedclass · Answer

(C) compound is aromatic if it satisfies the following conditions:$1$. It must be cyclic.$2$. It must be planar.$3$. It must have a fully conjugated system of $\pi$ electrons.$4$. It must follow $H$ückel's rule,i.e.,it must contain $(4n+2) \pi$ electrons,where $n = 0, 1, 2, ...$.Let us analyze the given options:- Option $(A)$: The cyclopentadienyl cation has $4 \pi$ electrons. It is anti-aromatic.- Option $(B)$: The cyclohexadienyl cation is non-planar and non-aromatic.- Option $(C)$: The tropylium cation (cycloheptatrienyl cation) has $6 \pi$ electrons $(n=1)$. It is cyclic,planar,and fully conjugated. Thus,it is aromatic.- Option $(D)$: The cyclooctatrienyl cation is non-planar and non-aromatic.Therefore,the correct option is $(C)$.
