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 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.
Resonance structures are sets of Lewis structures that describe the delocalization of electrons in a polyatomic ion or a molecule. In many cases, a single Lewis structure fails to explain the bonding in a molecule/polyatomic ion due to the presence of partial charges and fractional bonds in it.
These questions cover all aspects of resonance in organic chemistry, from identifying resonance forms, understanding partial charges, ranking the relative importance of resonance forms, and drawing curved arrows to interconvert resonance forms.
Definition. Resonance structures are different Lewis structures for a molecule or ion that cannot be described by a single Lewis structure. These structures depict the same arrangement of atoms but involve different placements of electrons, particularly the locations of bonds and lone pairs.

16 gru 2021 · The discussion of resonance effect heavily relies on the understanding of resonance structures. Here we will focus on how to draw resonance structures (or resonance contributors) for organic chemistry species, and how to compare the relative stabilities between the structures.
