Vedclass · Answer

(B) The stability of carbocations is determined by factors such as resonance,hyperconjugation,and inductive effects. $1$. $tert$-Butyl carbocation $(CH_3)_3C^+$ is stabilized by $9$ hyperconjugative hydrogens. $2$. $1$-Phenylethyl carbocation $C_6H_5-CH^+(CH_3)$ is stabilized by resonance with the phenyl ring,which is a much stronger stabilizing effect than hyperconjugation. $3$. $2$-Nitroethyl carbocation is highly unstable due to the strong electron-withdrawing effect of the $-NO_2$ group. $4$. Isopropyl carbocation $(CH_3)_2CH^+$ is stabilized by $6$ hyperconjugative hydrogens. Comparing these,the $1$-phenylethyl carbocation is the most stable due to resonance stabilization by the aromatic ring.

In which of the following compounds,the $C-Cl$ bond ionization shall give the most stable carbocation?
