Vedclass · Answer

(A) The stability of carbocations is determined by the electronic effects of the substituents attached to the positively charged carbon atom.$(I)$ $CH_3O-C_6H_4-CH_2^+$: The $-OCH_3$ group exerts a strong $+M$ (mesomeric) effect,which significantly stabilizes the carbocation.$(II)$ $C_6H_5-CH_2^+$: This is a benzyl carbocation,stabilized by resonance with the benzene ring.$(III)$ $CH_3-C_6H_4-CH_2^+$: The $-CH_3$ group exerts a $+I$ (inductive) effect and hyperconjugation,providing moderate stabilization.$(IV)$ $CH_3-CH_2-CH_2^+$: This is a primary alkyl carbocation,which is the least stable among the given options.Comparing these,the order of stability is: $IV < II < III < I$.

Label	Carbocation
$1$	$CH_3-CH^+-CH_3$
$2$	$CH_3^+$
$3$	$(CH_3)_3C^+$
$4$	$CH_3-CH_2^+$
