Q.
The correct stability order of carbocation is [2024]

1 ${({CH}_{3})}_{3} C^{+} > {CH}_{3} - \overset{+}{C} H_{2} > {({CH}_{3})}_{2} \overset{+}{C} H > \overset{+}{C} H_{3}$

2 $\overset{+}{C} H_{3} > {({CH}_{3})}_{2} \overset{+}{C} H > {CH}_{3} - \overset{+}{C} H_{2} > {({CH}_{3})}_{3} \overset{+}{C}$

3 ${({CH}_{3})}_{3} \overset{+}{C} > {({CH}_{3})}_{2} \overset{+}{C} H > {CH}_{3} - \overset{+}{C} H_{2} > \overset{+}{C} H_{3}$

4 $\overset{+}{C} H_{3} > {CH}_{3} - \overset{+}{C} H_{2} > {CH}_{3} - {CH}_{\overset{|}{{CH}_{3}}}^{+} > {({CH}_{3})}_{3} C^{+}$

Ans.
(3)

Stability of carbocations follows the order: 3° > 2° > 1°. This is due to more hyperconjugation and +I stability in higher degree carbocations.

Q. The correct stability order of carbocation is [2024]

1 (CH3)3C+>CH3-C+H2>(CH3)2C+H>C+H3

2 C+H3>(CH3)2C+H>CH3-C+H2>(CH3)3C+

3 (CH3)3C+>(CH3)2C+H>CH3-C+H2>C+H3

4 C+H3>CH3-C+H2>CH3-CHCH3|+>(CH3)3C+

Ans. (3) Stability of carbocations follows the order: 3° > 2° > 1°. This is due to more hyperconjugation and +I stability in higher degree carbocations.
