Which of the following chemical species exhibit resonance to stabilize their structures? — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Ozone ($O_3$), Carbonate ($CO_3^{2-}$), and Nitrate ($NO_3^-$) all have multiple canonical forms due to delocalized $\pi$ electrons. $SiO_2$ in its solid state forms a giant 3D covalent network structure via single $\sigma$ bonds and does not exhibit resonance.
