The interaction of the σ-bond system with the π-electron system in molecules of type {ie427-01} is easily determined for the symmetrical CH3 group by isolating the π-component from the system of three σ-bonds; CH3 is thus treated as a C=X quasivinyl group. The theory is extended to unsymmetrical groups. Hyperconjugation is analyzed through the electron density of orbitals responsible for hyperconjugative interactions, which cannot be detected by means of conventional electron-density-based calculations. This interaction is detected through the π electron density topology, by excluding σ electron density from the total.

Other types of Hyperconjugation Occasionally, electron density will be donated from a filled 𝜋 or p orbital into an adjacent σ* orbital. This is known as negative hyperconjugation. Other times, electron density will be donated from a p orbital into an adjacent 𝜋* orbital; the result is an overall neutral charge on the molecule.

Nov 27, 2015 · The stability of a carbocation depends on hyperconjugation and resonance. The more substituted a carbocation is, meaning the more carbons that are bonded to it, the more stable it is because there are more carbons available that can temporarily delocalize their electrons to the empty p orbital of the carbocation in order to stabilize it.
In molecular orbital terms, hyperconjugation is the overlap of the filled sigma orbitals of the C-H bonds adjacent to the carbocation with the empty "p" orbital on the positively charged carbon atom (see diagram below). This electronic "spillover" helps delocalize the positive charge onto more than one atom.

Tautomerism, the existence of two or more chemical compounds that are capable of facile interconversion, in many cases merely exchanging a hydrogen atom between two other atoms, to either of which it forms a covalent bond. Unlike other classes of isomers, tautomeric compounds exist in mobile different types of s orbitals. These s orbitals are mixed with p orbital via through-bond interactions. As a result, through-bond interactions, such as hyperconjugation, bring about the orbital rehybridization (pyramidalization) and tilting, leading to the desired transition structure. Nov 04, 2016 · Relative hyperconjugation strength depends on the isotope type of the Hydrogen. Hydrogen has a greater strength compared to Deuterium (D) and Tritium (T).
