How many hyperconjugative structures (equivalent to the number of -hydrogens) stabilize the -butyl c — Reaction Mechanism Chemistry Question
Question
How many hyperconjugative structures (equivalent to the number of $\alpha$ -hydrogens) stabilize the $tert$ -butyl carbocation, $(CH_3)_3C^+$?
Answer: 9
💡 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 $3 \times 3 = 9$.
