What is the definition of hyperconjugation?
Understand the Problem
The question is asking for a definition of hyperconjugation, a concept in chemistry related to molecular interactions and stability. We will provide a concise and clear explanation of this term.
Answer
The delocalization of electrons from a σ-bond to an adjacent empty or partially filled p orbital, increasing molecule stability.
In organic chemistry, hyperconjugation refers to the delocalization of electrons from a σ-bond (usually C-H or C-C) to an adjacent empty or partially filled p orbital, or a π orbital, resulting in increased stability of the molecule.
Answer for screen readers
In organic chemistry, hyperconjugation refers to the delocalization of electrons from a σ-bond (usually C-H or C-C) to an adjacent empty or partially filled p orbital, or a π orbital, resulting in increased stability of the molecule.
More Information
Hyperconjugation can also be described as a type of resonance involving σ bonds that increases the stability of carbocations, radicals, and alkenes.
Tips
A common mistake is to confuse hyperconjugation with regular resonance, which typically involves π bonds rather than σ bonds.
