Question

10 mark for review resonance is most commonly used to describe the bonding in molecules of which of the following? a co₂ b o₃ c h₂o d sf₆

Explanation:

Resonance is used when a molecule can be represented by multiple Lewis - structures. Ozone ($O_3$) has resonance structures due to the delocalization of electrons in its double - bond system. $CO_2$ has a linear structure with two double bonds and no resonance in the common sense. $H_2O$ has a bent structure with single bonds and no resonance. $SF_6$ has a octahedral geometry with no resonance for its bonding.

Answer:

B. $O_3$
