Arrange the following carbocations in order of increasing stability [A](CH3)3CC+H2[A] (CH_3)_3C\overset{+}{C}H_2 \, , [B](CH3)3C+[B][B] (CH_3)_3\overset{+}{C}\, [B] , [C]CH3CH3C+H2[C] CH_3CH_3C^+H_2\, , [D]CH3C+HCH2CH3[D] CH_3\overset{+}{C}HCH_2CH_3 \,

A

D<C<B<AD < C < B < A

B

C<D<A<BC < D < A < B

C

A<C<D<BA < C < D < B

D

B<D<C<AB < D < C < A

Answer

A<C<D<BA < C < D < B

Explanation

Solution

The order of increasing stability of carbocations is

Carbocation [A][A] is least stable and converts to more stable 3?3? carbocation through rearrangement.
