Resonance in chemistry is a tool used (of a prevalent matter in organic chemistry) to represent certain types of molecular structures. Resonance is a key component of theory of bond of valence and emerges when no conventional model using only the simple, double or triple bonds can explain all the properties observed of the molecule. The dot diagrams of Lewis often cannot represent the true electronic structure of a molecule. While one can only show the simple covalent bonds, double or triple using these diagrams, one notes that the molecule observed does not match either these structures but rather has properties in certain an intermediary of direction to the latter. Structures of resonance are then used to bring closer the true electronic structure.
