What is the correct order of decreasing stability of the following cations

I) CH3−C⊕H−CH3C{H_3} - \mathop C\limits^ \oplus H - C{H_3}

II) CH3−C⊕H−OCH3C{H_3} - \mathop C\limits^ \oplus H - OC{H_3}

III) CH3−C⊕H−OCH3C{H_3} - \mathop C\limits^ \oplus H - OC{H_3}
View answer and explanation
Correct option: A
II > I > III
Option B (II > I > III) is correct because the carbocation is stabilized by the electron-donating effect of the methoxy group in II, and destabilized by the inductive effect in III.
