How many total -hydrogen atoms are available to provide stability via hyperconjugative structures in — GOC and Organic Chemistry Basics Chemistry Question

💡 Solution & Explanation

The tertiary butyl carbocation consists of a central positively charged carbon bonded to three methyl groups. Each methyl group has 3 hydrogens on the $\alpha$ -carbon. Therefore, there are $3 \times 3 = 9$ total $\alpha$ -hydrogens capable of hyperconjugation.
