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 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.
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 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.
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.
Resonance structure is a concept in organic chemistry that describes the delocalization of electrons within a molecule, resulting in the existence of multiple valid Lewis structures that contribute to the overall bonding and stability of the compound.
Definition. Resonance structures are different ways of drawing the same molecule that show how electrons can be distributed among its bonds. This concept helps to illustrate the delocalization of electrons within certain molecules, which is crucial for understanding their reactivity and stability.
