The theory of resonance was developed primarily by Pauling in the 1930s. According to this theory , many molecules and ions are best described by writing two or more Lewis structure and considering the realmolecule of ion to be a composite of these structures .They are also sometimes referred to as resonance structures or resonance contributors . We show that the real molecule or ion is a resonance hybrid of the various contributing structures by interconnecting them with double headed arrows . Resonance structures are not in equilibrium with each other . . Find out the stability order of intermediate .
