Vedclass · Answer

(B) To determine the stability of carbocations,we consider inductive effects,resonance,and hyperconjugation.$(A)$ $CH_3-CH^+-OCH_3$ is more stable than $CH_3-CH^+-CH_3$ due to the strong $+M$ effect of the $-OCH_3$ group.$(B)$ $CH_3-CH_2-CH^+-CH_3$ is a secondary $(2^\circ)$ carbocation with $5$ $\alpha$-hydrogens. $CH_2=CH-CH_2-CH_2^+$ is a primary $(1^\circ)$ carbocation with $2$ $\alpha$-hydrogens. The first is more stable.$(C)$ The cyclohex$-1-$enylmethyl carbocation is more stable than the cyclohexylmethyl carbocation because the double bond is conjugated with the carbocation center,allowing for resonance stabilization.$(D)$ $CH_3-N(CH_3)-C^+(CH_3)_2$ is significantly more stable than the alkyl carbocation due to the strong $+M$ effect of the nitrogen lone pair.Thus,in pair $(B)$,the first ion is more stable than the second.
