In organic chemistry, hyperconjugation (σ-conjugation or no-bond resonance) refers to the delocalization of electrons with the participation of bonds of primarily σ-character.

According to hyperconjugation, also known as no-bond resonance, and a variant of resonance theory, electron delocalization could also occur via parallel overlap of p orbitals with hybridized …

Hyperconjugation is the stabilising interaction that results from the interaction of the electrons in a σ-bond (usually C-H or C-C) with an adjacent empty or partially filled p-orbital or a π-orbital to …

It is also important to note that the effect of hyperconjugation is stronger than the inductive effect. For example, the positive inductive effect of ethyl group is stronger than that of methyl group.

Hyperconjugation is an important electronic effect in organic chemistry that involves the delocalization of electrons in sigma (σ) bonds to stabilize adjacent unsaturated systems like …

The phenomenon of hyperconjugation (or σ-conjugation) may simply be defined as the delocalization of electrons with the participation of bonds of primarily σ-character.

Prediction: Substituents with Low-Lying LUMOs will Accelerate the Sn2 by Stabilizing Electron Density from Nucleophile and Leaving Group through Hyperconjugation

Nov 18, 2025 · Due to increased hyperconjugation, the stability of alkenes increases with the number of α-hydrogens. More α-hydrogens allow for more contributing hyperconjugative …

In the formalism that separates bonds into σ σ and π π types, hyperconjugation is the interaction of σ σ bonds (e.g. C H, C C, etc.) with a π π network.

Jun 4, 2025 · Hyperconjugation is a phenomenon where the delocalization of electrons occurs through the overlap of a σ-bond with a p-orbital or a π-bond, resulting in the stabilization of the …
