Vedclass · Answer

(C) The reaction of cycloheptatrienyl bromide with $AgNO_3$ leads to the formation of the tropylium cation $(C_7H_7^+)$ and $AgBr$ precipitate.The tropylium cation is a $6\pi$ electron system,which follows $H$ückel's rule ($4n+2$ where $n=1$),making it aromatic.Aromatic compounds possess high resonance energy due to the delocalization of $\pi$ electrons.Since the product is an ionic salt (tropylium nitrate),it has a high dipole moment and is soluble in polar solvents.Therefore,the statement that the product has less resonance energy is incorrect,as the aromatic tropylium cation is highly stable and has significant resonance energy.
