Resonance structures are used when one Lewis structure for a single molecule cannot fully describe the bonding that takes place between neighboring atoms relative to the empirical data for the actual bond lengths between those atoms.

All resonance structures are stable and equally contribute to the resonance hybrid in equivalent resonance structures. In non-equivalent resonance structures, one resonance structure is better than the other, and all have different stabilities.
In this tutorial on resonance structures, you will learn what resonance structures are and how to find all of the possible resonance structures a molecule has. You will also learn how to identify and compare the stability among these structures.
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.
30 sty 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.
The stability a species gains from having charge delocalization through resonance contributors is called the resonance stabilization effect. The greater the number of resonance contributors, the greater the resonance stabilization effect and the more stable the species is.
The Resonance stabilization effect (also known as the resonance effect), as briefly mentioned in Section 1.3, is one of the fundamental concepts of Organic Chemistry and has broad applications. The discussion of the resonance effect heavily relies on the understanding of resonance structures.
