Question

Difference between hyperconjugation and reverse hyperconjugation

Answer 1

Answer:

Explanation:

“Reverse hyperconjugation” is what's usually called negative hyperconjugation, I think. In negative hyperconjugation, the electron interaction is directed from the pi bond to the sigma bond rather than from sigma to pi. In other words, there is a movement of electron density towards the sigma bond.

Hyperconjugation is the stabilising interaction that results from the interaction of the electrons in a σ-bond (usually C-H or C-C) with an adjacent empty or partially filled p-orbital or a π-orbital to give an extended molecular orbital that increases the stability of the system.
