Vedclass · Answer

(A) The stability of carbocations is determined by the electronic effects of the substituents attached to the benzene ring.$(1)$ $CH_3O-$ group is a strong electron-donating group by resonance ($+M$ effect),which significantly stabilizes the carbocation.$(2)$ The unsubstituted benzyl carbocation $(C_6H_5-CH_2^+)$ has only resonance stabilization from the phenyl ring.$(3)$ $CH_3-$ group is an electron-donating group by hyperconjugation and inductive effect ($+I$ effect),which provides moderate stabilization.Therefore,the stability order is $(1) > (3) > (2)$,which is equivalent to $2 < 3 < 1$.

Consider the following carbocations. What is the relative stability order of these carbocations?
$(1)$ $CH_3O-C_6H_4-CH_2^+$
$(2)$ $C_6H_5-CH_2^+$
$(3)$ $CH_3-C_6H_4-CH_2^+$
