Vedclass · Answer

(D) The stability of carbocations is determined by factors such as aromaticity,resonance,and hyperconjugation.$C$ is the tropylium cation $(C_7H_7^+)$,which is aromatic ($6 \pi$ electrons) and therefore the most stable.$A$ is the triphenylmethyl carbocation,which is stabilized by resonance with three phenyl rings.$B$ is the diphenylmethyl carbocation,which is stabilized by resonance with two phenyl rings.$D$ is a secondary carbocation ($sec-butyl$ cation),which is stabilized only by hyperconjugation and inductive effects.Thus,the order of stability is $C > A > B > D$.

The correct order of stability of the following carbocations is:
