$(C_6H_5)_3C^+$

Vedclass · Answer

(C) The correct answer is $C$. In the triphenylmethyl carbonium ion,the $\pi$ electrons of all three benzene rings are delocalized with the vacant $p$-orbital of the central carbon atom.This leads to extensive resonance stabilization.It is the most stable among the given carbonium ions.The ion $(CH_3)_3C^+$ is stabilized by hyperconjugation,which is a weaker effect compared to the extensive resonance provided by three phenyl groups.
