The order of increasing stability of carbocations is

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

Q. Arrange the following carbocations in order of increasing stability
$[A] (C H_{3})_{3} C C + H_{2}$ , $[B] (C H_{3})_{3} C +$ ,
$[C] C H_{3} C H_{3} C^{+} H_{2}$ , $[D] C H_{3} C + H C H_{2} C H_{3}$

$D < C < B < A$

$C < D < A < B$

$A < C < D < B$

$B < D < C < A$

The order of increasing stability of carbocations is

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