A Short Note On Resonance Definition - unacademy.com

WebResonance. Resonance, also known as mesomerism, is a means of defining bonding in specific molecules or ions in valence bond theory by combining many contributing structures (or forms, also known as canonical structures or resonance structures) into the resonance hybrid (or hybrid structure). It’s especially useful for explaining delocalized ... Under the framework of valence bond theory, resonance is an extension of the idea that the bonding in a chemical species can be described by a Lewis structure. For many chemical species, a single Lewis structure, consisting of atoms obeying the octet rule, possibly bearing formal charges, and connected by bonds of positive integer order, is sufficient for describing the chemical bondin…
