Question

The hyperconjugative stabilities of tertiary butyl carbocation and but-2−ene, respectively, are due to, σ → p (empty) and σ → π * electron delocalisations., σ → σ * and σ → π electron delocalisations., σ → p (filled) and σ → π electron delocalisations., p (filled) → σ * and σ → π * electron delocalisations.

MARKS App · Accepted Answer

Hyperconjugation involves delocalisation of σ electron of α C—H with π empty p-orbital. It increases stability of carbocation, free radical and alkenes by decreasing energy. C H 3 - C H = C H 2 ( σ - π * electron) delocalization
