Definition

Resonating structures are different molecular structures that are mentally melded together to represent resonance.

Explanation

Resonance structure involves different ways of drawing the Lewis dot structure for a compound. The corresponding Lewis structures are called resonance structures that represent the movement of electrons in the molecule.

Examples –

Notice the different ways in which the π bonds are structures around the atoms.
