Question

What is hyperconjugation effect ?

Answer 1

Inductive effects are mostly associated on the basis of an electronic movement via sigma bonds, which widely differs and is actually attributed to change in electronegativity.

If taking resonance effect it's the extension of the Hyperconjugation Effect which involves association with electron movements through $\textbf\boxed{"p" Orbitals}$ and delocalisation of $\pi - Electrons$ of more than two conjugated double bonds or simply $\pi - Electrons$ of a particular double bonding or not exhibiting bonding, this means, suppose n-electrons of a heteroatom, here, the Hyperconjugation will involve delocalisation of presently weak bond called $\sigma\textbf{ - Electrons}$ by this a follow up of $\sigma-\pi$ conjugations making the $\sigma\textbf{- orbital}$ to overlap the $\textbf{p - Orbitals}$ of a single $\pi\textbf{-Bond}$, hence, it's name has been derived as $\textbf{No Bond Resonance}$.

In a summarised view, Hyperconjugation effect or also known as $\boxed{Baker-Nathan \: Effect}$ which cannot be described or vindicate the presence of an inductive effect being the only method for explanations for substituents. To make it even more clearer; Hyperconjugation is the inverse of an inductive effect, that is, making the orders reversed and performing a corresponding reaction between Electrons of single $\pi\textbf{-Bonds}$ and an unsaturated system. The term of $\textbf{no-bond resonance}$ was solely being used to describe the type of electronic interactions by bondings, though the contribution of chemical structure is also taken into consideration.

Answer 2

Answer:

Hyperconjugation effect is a permanent effect in which localization of σ electrons of C-H bond of an alkyl group directly attached to an atom of the unsaturated system or to an atom with an unshared p orbital takes place.
