How many hyperconjugative structures (equivalent to the number of -hydrogens) stabilize the -butyl c — Reaction Mechanism Chemistry Question

💡 Solution & Explanation

The central positively charged carbon atom is bonded directly to three methyl groups. Each methyl group contains 3 $\alpha$ -hydrogens. The total number of $\alpha$ -hydrogens participating in hyperconjugation is $3 \times 3 = 9$.
