A tertiary butyl carbocation is more stable than a secondary butyl carbocation because of which of the following?Tertiary butyl carbocation has 9 $\alpha$-H atoms, while secondary butyl carbocation has 5 $\alpha$-H atoms. The more the number of $\alpha$-H atoms, the greater the hyperconjugation, and hence the greater the stability of the carbocation.
