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, also variously known as resonance structures or canonical structures) into a resonance hybrid (or hybrid structure) in valence bond theory.
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 into a resonance hybrid in valence bond theory.
Jan 30, 2023 · Resonance is a way of describing delocalized electrons within certain molecules or polyatomic ions where the bonding cannot be expressed by a single Lewis formula. A molecule or ion with such delocalized electrons is represented by several resonance structures.
Oct 2, 2019 · Resonance Definition: Resonance is a method of describing the delocalized electrons in some molecules where the bonding cannot be explicitly expressed by a single Lewis structure. Each individual Lewis structure is called a contributing structure of the target molecule or ion .
Jun 2, 2024 · Resonance is an imaginary concept developed to explain the unexceptional stability of some molecules. It is the wandering of pi electrons within a molecule.
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 arises when more than one valid Lewis structure can be drawn for a molecule or ion. The overall electronic structure of the molecule or ion is given by the weighted average of these resonance structures and is referred to as the resonance hybrid. Created by Sal Khan. Questions.

Feb 2, 2024 · In chemistry, the definition of resonance is a phenomenon describing the delocalization of electrons within certain molecules or polyatomic ions by combining different contributing...
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.
Jun 20, 2024 · Resonance structures are the Lewis structure sets that describe the electron's delocalization in a molecule or a polyatomic ion. In most of the cases, a single Lewis structure has always failed to explain the bonding in either a polyatomic or molecule ion because of the presence of fractional bonds and partial charges in it.
