Vedclass · Answer

(B) The stability of carbocations is determined by inductive effects,hyperconjugation,and resonance effects.$III$ is a primary $(1^{\circ})$ carbocation,which is the least stable.$IV$ is a secondary $(2^{\circ})$ carbocation,which is more stable than $III$ due to hyperconjugation.$I$ is a tertiary $(3^{\circ})$ carbocation,which is more stable than $IV$ due to greater hyperconjugation and $+I$ effect.$II$ is a carbocation stabilized by the strong $+M$ (mesomeric) effect of the lone pair on the oxygen atom of the $-OCH_3$ group,making it the most stable among the given options.Therefore,the correct order of stability is $III < IV < I < II$.

The stability of the following carbocations follows the order:
$I. (CH_3)_3C^{\oplus}$
$II. (CH_3)_2C^{\oplus}(OCH_3)$
$III. CH_3CH_2CH_2CH_2^{\oplus}$
$IV. CH_3CH^{\oplus}CH_2CH_3$
