$I \approx III > II$

Vedclass · Answer

(C) In $(I)$ and $(III)$,the positive charge is delocalized through resonance,and the carbocation character is stabilized by the presence of an adjacent alkyl group. Specifically,$(I)$ is a secondary $(2^\circ)$ allylic carbocation,and $(III)$ is a primary $(1^\circ)$ allylic carbocation. However,in $(I)$,the positive charge is on a secondary carbon,while in $(III)$,it is on a primary carbon. In $(II)$,the positive charge is on a primary carbon and is allylic. Comparing the resonance structures and the inductive effects,$(I)$ and $(III)$ show greater stability due to the nature of the allylic system and the electron-donating effects of the methyl group. Thus,the correct order is $(I) \approx (III) > (II)$.
