While benzyl carbocations are resonance stabilized, the tertiary butyl carbocation () is found to be — GOC and Organic Chemistry Basics Chemistry Question

💡 Solution & Explanation

In the tertiary butyl carbocation, the presence of 9 $\alpha$ -hydrogen atoms contributes towards extensive hyperconjugation (9 hyperconjugative structures). This massive delocalization of $\sigma$ electrons makes it even more stable than the benzyl carbocation.
