Q.
The most stable carbocation, among the following is: [2019]

1 ${({CH}_{3})}_{3} C - \overset{+}{C} H - {CH}_{3}$

2 ${CH}_{3} - {CH}_{2} - \overset{+}{C} H - {CH}_{2} - {CH}_{3}$

3 ${CH}_{3} - \overset{+}{C} H - {CH}_{2} - {CH}_{2} - {CH}_{3}$

4 ${CH}_{3} - {CH}_{2} - \overset{+}{C} H_{2}$

Ans.
(3)

Among the given carbocations,

${CH}_{3} - \overset{+}{C} H - {CH}_{2} - {CH}_{2} - {CH}_{3}$ is most stable carbocation. As it consists of maximum number of $α$ -hydrogens and stablised by hyperconjugation.
