Triphenylmethyl carbocation

Vedclass · Answer

(B) The stability of carbocations is determined by the dispersal of the positive charge.Alkyl groups stabilize carbocations through the inductive effect and hyperconjugation,with the order being: $3^\circ 	ext{alkyl} > 2^\circ 	ext{alkyl} > 1^\circ 	ext{alkyl} > 	ext{methyl}$.However,resonance stabilization is significantly more effective than inductive effects. The triphenylmethyl carbocation is stabilized by resonance with three phenyl rings,which delocalize the positive charge over a large number of carbon atoms.Therefore,the triphenylmethyl carbocation is the most stable among the given options.
