Vedclass · Answer

(D) The carbonate ion $(CO_3^{2-})$ exhibits resonance,where the three $C-O$ bonds are equivalent due to the delocalization of $\pi$ electrons over the three oxygen atoms.In the resonance hybrid,each $C-O$ bond has a bond order of $1.33$ (or $4/3$).Since all three $C-O$ bonds are identical in the resonance hybrid,they all possess the same bond length.Therefore,the correct order is $I = II = III$.

Taking into account hybridization and resonance effects,rank the following $C-O$ bonds in order of decreasing bond length. The structure provided is the carbonate ion $(CO_3^{2-})$.
