Define hyper conjugation in chemistry
WebIn organic chemistry, negative hyperconjugation is the donation of electron density from a filled π- or p-orbital to a neighboring σ * -orbital. [1] This phenomenon, a type of resonance, can stabilize the molecule or transition state. [2] It also causes an elongation of the σ-bond by adding electron density to its antibonding orbital. WebHyperconjugation definition: (organic chemistry) A weak form of conjugation in which single bonds interact with a conjugated system.
