Study Notes
Valence Bond Theory and Resonance
- In valence bond theory, resonance is particularly valuable for analyzing delocalized electrons.
- A resonance hybrid represents a mix of possible Lewis structures that describe the bonding in molecules or polyatomic ions.
- Resonance is also known as mesomerism in chemistry.
- Atoms in a single Lewis structure typically obey the octet rule in describing chemical bonding.
- A single Lewis structure is often insufficient for describing the bonding in many chemical species because it cannot account for delocalization of electrons.
- Resonance allows for delocalization of electrons in valence bond theory.
- Delocalized bonding cannot be expressed by a single Lewis structure.
- The primary purpose of using resonance in describing chemical bonding is to account for the delocalization of electrons.
- A resonance hybrid of possible Lewis structures is sufficient for describing the chemical bonding in many chemical species according to valence bond theory.
