The Lewis structure of which molecule requires resonance structures?A.) MgCl2B.) SiO2C.) SO2D.) OCl2
inna [77]

Answer:  C.) SO2

Explanation:  Sulfur Dioxide is the gaseous molecule which can show the resonance through lewis dot structure due to the presence of lone pairs of electrons present on all of the three atoms of the molecules. Moreover , Sulphur forms pie bond with the oxygen using p orbitals which forms a network of the conjugated system that help to elaborate the reason of the formation of the resonance structure.

Options (a), (b), and (d) cannot form resonating structures as they involve the formation of the chemical bonds through single sigma bond.
