Resonance structure

Resonance structures are different ways of drawing the same molecule to show how electrons are distributed. In some molecules, electrons aren’t fixed in one spot but can move between different bonds or atoms. Since these electrons are delocalized, chemists represent these molecules with multiple valid structures, called resonance structures, to illustrate the possible arrangements. The actual molecule is a hybrid of all these structures, resulting in a more accurate understanding of its shape and properties. Resonance helps explain phenomena like stability, reactivity, and bond strength in complex molecules.
