Question
According to structural theory, which of the following reactive intermediates or stable molecules can directly derive significant thermodynamic stabilization from hyperconjugation?
Answer: A,B,D
π‘ Solution & Explanation
Hyperconjugation stabilizes electron-deficient species with empty p-orbitals (carbocations) or half-filled p-orbitals (free radicals), and it also stabilizes $\pi$ -systems (alkenes) via $\sigma \rightarrow \pi^*$ overlap. Carbanions are electron-rich and cannot be stabilized by hyperconjugative electron donation.
