Hyperconjugation (No-bond Resonance)

 

Hyperconjugation (No-bond Resonance)

There is another type of delocalization, which involves σ-electrons called Hyperconjugation.

It may be regarded as a σ-π orbital overlap analogous to the π-π orbital overlap.

In hyperconjugation, the sigma C-H bond on the alpha carbon is delocalized with the empty p-orbital of a C= or a carbocation. As a result, H+ does not change its position.
