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.
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.
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.
Consider the thiocyanate ion, SCN – (carbon is the central atom), and its resonance structures. Identify the structure that contributes the most and the structure that contributes the least to the resonance hybrid.
