hy·per·conjugation \| ̷ ̷ ̷ ̷+\ noun Etymology: hyper- + conjugation : resonance in an organic chemical structure that involves as part of the resonance hybrid the separation of a proton from a methyl or other alkyl group situated next to an electron-deficient unit (as a double bond or carbonium ion), the electrons released by the proton tending to move toward the electron-deficient function with resultant stabilization of the entire structure (as in a trisubstituted propylene H−CH2 CR = CR2↔H+CH2 = CR−CR2-) — called also no-bond resonance |
