hyperconjugation
This term is a specialized technical expression used almost exclusively within organic chemistry. It describes a specific electronic effect that explains why certain molecular structures, such as tertiary carbocations, are more stable than others. It is a more subtle form of electron delocalization than resonance, involving sigma bonds rather than pi systems.
As a technical scientific term, it is treated as an uncountable noun. It refers to a chemical phenomenon or process rather than a discrete object, meaning it does not have a plural form in standard chemical discourse.
Meanings
Examples
The stability of the tertiary carbocation is primarily due to hyperconjugation.
Does hyperconjugation explain why trans-alkenes are more stable than cis-alkenes?
I need to remember that hyperconjugation involves sigma bond overlap.
Hyperconjugation provides a stabilizing effect by delocalizing electron density.
The professor explained how hyperconjugation affects the bond length in substituted ethenes.
Wait, is this an inductive effect or is it actually hyperconjugation?
The Baker-Nathan effect is a classic example of hyperconjugation in organic molecules.
Hyperconjugation occurs when the C-H sigma bond aligns with the empty p-orbital.
