Question

Which of the following hydrocarbon molecules are capable of exhibiting hyperconjugation ($\sigma-\pi^*$ or $\sigma-p$ overlap) in their ground state or as a reactive intermediate?

Correct answer: A,B,C. Propene has 3 -H next to a bond. Toluene has 3 -H next to the aromatic system. Ethyl carbocation has 3 -H next to an empty p-orbital. Benzaldehyde has no hybridized carbon with -hydrogens attached to the ring, so it cannot show hyperconjugation.
