Hyperconjugation is the stabilising interaction that results from the interaction of the electrons in a s-bond (usually C-H or C-C) with an adjacent empty (or partially filled) p-orbital or a p-orbital to give an extended molecular orbital that increases the stability of the system.

The concept of hyperconjugation was developed by Baker and Nathan and is also known as Baker and Nathan effect. According to this concept, if an alkyl group carrying at least one hydrogen atom is attached to an unsaturated carbon atom, it releases the electrons of carbon-hydrogen single bond towards the multiple bond. For example, the hyper conjugation in propene is shown below:
