What is Hyperconjugation

Definition of Hyper conjugation What is Hyperconjugation? Hyperconjugation is stabilizing interactions that are results from interaction of electrons in a sigma (σ-bond) (usually C-H or C-C) with an adjacent empty or partially-filled p-orbital or a pi (π) orbital to give an extended molecular orbitals that increases stability of system. Hyper-conjugation is chemistry terminology and also known as Sigma …
