WebThe delocalization of σ-electrons or lone pair of electrons into adjacent π -orbital or p-orbital is called hyperconjugation. It occurs due to overlapping of σ-bonding orbital or the orbital containing a lone pair with adjacent π -orbital or p-orbital. It is also known as "no bond resonance" or "Baker-Nathan effect".
