Question

describe hyperconjugation with example​

Answer 1

Answer:

In the formalism that separates bonds into σ and π types, hyperconjugation is the interaction of σ-bonds (e.g. C-H, C-C, etc.) ... The interaction between filled π or p orbitals and adjacent antibonding σ* orbitals is referred to as "negative hyperconjugation", as for example in the fluoroethyl anion: RADOM (1982).
