12 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
Answer
Brief Explanations:
Resonance is a concept in chemistry used when a molecule can be represented by multiple Lewis - structures. Ozone ($O_3$) has resonance structures due to the delocalization of electrons. In $CO_2$, the bonding can be well - described by a single Lewis structure with double bonds. In $H_2O$, the bonding is mainly covalent with no resonance. In $SF_6$, the bonding is based on its octahedral geometry and there is no resonance.
Answer:
B. $O_3$
