WebOct 22, 2024 · Hyperconjugation Effect [Click Here for Previous Years' Questions] To understand hyperconjugation effect, consider an example of CH 3 CH 2 + (ethyl cation) in which the positively charged carbon atom has an empty p orbital. One of the three C-H bonds of the methyl group can align in the plane of the empty p orbital, and the electrons … WebAsk Question. Hyperconjugation involves the donation of electrons from a filled orbital (commonly the bonding C-H sigma molecular orbital) into an adjacent/partially occupied p-orbital (for instance an adjacent carbocation) leading to stabilisation. The tag should be applied to questions where hyperconjugation is involved, even if the question ...

In organic chemistry, negative hyperconjugation is the donation of electron density from a filled π- or p-orbital to a neighboring σ -orbital. This phenomenon, a type of resonance, can stabilize the molecule or transition state. It also causes an elongation of the σ-bond by adding electron density to its antibonding orbital. Negative hyperconjugation is seldom observed, though it can be most commo…
WebHyperconjugation. 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.
