Resonance Structures. 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.
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.
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.
Revision notes on 4.2.1 Resonance Structures for the DP IB Chemistry: HL syllabus, written by the Chemistry experts at Save My Exams.
30 sty 2023 · 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.
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.
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.
