Resonance (chemistry) - Wikipedia
In chemistry, resonance, also called mesomerism, is a way of describing bonding in certain molecules or polyatomic ions by the combination of several contributing structures (or forms, [1] also variously known as resonance structures or canonical structures) into a resonance hybrid (or hybrid structure) in valence bond theory.

2023年1月30日 · Resonance is a mental exercise within the Valence Bond Theory of bonding that describes the delocalization of electrons within molecules. It involves constructing multiple Lewis structures that, when combined, represent the full electronic structure of the molecule.
8.6: Resonance Structures - Chemistry LibreTexts
Some molecules have two or more chemically equivalent Lewis electron structures, called resonance structures. Resonance is a mental exercise and method within the Valence Bond Theory of bonding that describes the delocalization of electrons within molecules.

Resonance Structures: Definition, Examples, and How to Draw
Resonance is a technique of describing the delocalized electrons in a molecule or ion that a single Lewis structure cannot describe. It is a phenomenon that explains the shifting of non-bonding electrons and pi bonds within the molecule.
9.4: Resonance Lewis Structures - Chemistry LibreTexts
2020年10月20日 · Resonance occurs when we can draw two or more legitimate Lewis structures for the same molecule. Resonance only occurs when a molecule has at least one double bond. Molecules with only single bonds never show resonance. Resonance structures must all have the correct number of electrons and must all obey the octet rule.
