Hyperconjugation is a stabilizing interaction that results from the interaction of the electrons in a sigma (σ) bond (usually C-H or C-C) with an adjacent empty or partially filled p-orbital or a π-orbital. This interaction results in the delocalization of electrons, which can stabilize carbocations, radicals, and alkenes. Hyperconjugation is often referred to as "no-bond resonance" or "Baker-Nathan effect."
