Question

Can one say me what is RESONANCE STRUCTURE. ​

Answer 1

Answer:

Resonance structure are sets of Lewis structures that describe the delocalization of electrons in a polyatomic ion or molecule

Answer 2

${\huge{\underline{\underline{\mathfrak{\orange{Answer:-}}}}}}$

A molecule or ion with such delocalized electrons is represented by several contributing structures (also called resonance structures or canonical forms). Such is the case for ozone (O3), an allotrope of oxygen with a V-shaped structure and an O–O–O angle of 117.5°.
