Vedclass · Answer

(B) The stability of a carbocation is increased by the presence of electron-donating groups or atoms that can stabilize the positive charge through resonance or inductive effects.In option $B$,the $-OH$ group is attached to the carbon adjacent to the carbocation center. The oxygen atom of the $-OH$ group has lone pairs of electrons that can participate in resonance,donating electron density to the carbocation and significantly stabilizing it.In options $A$,$C$,and $D$,the $-OH$ group is either absent or too far away to provide significant resonance stabilization. In $C$,the $-OH$ group is attached to a carbon that is directly bonded to the carbocation,but the inductive effect of the electronegative oxygen atom actually destabilizes the carbocation. In $B$,the resonance effect of the lone pair on oxygen outweighs the inductive effect,making it the most stable.
