The delocalization of electrons due to overlap between p-orbital and sigma bond is called.

Step-by-step solution

Hyperconjugation is the delocalization of electrons due to the overlap between a bond (usually C-H or C-C) and an adjacent empty or partially filled p-orbital or a -orbital. Inductive effect involves the polarization of bonds due to electronegativity differences. Resonance involves the delocalization of electrons or lone pairs in parallel p-orbitals. Therefore, the given description corresponds to hyperconjugation. Answer: hyperconjugation
