Vedclass · Answer

(B) The carbonate ion $(CO_3^{2-})$ exhibits resonance due to the delocalization of $\pi$ electrons over the three oxygen atoms.There are $3$ equivalent resonance structures for the $CO_3^{2-}$ ion,as shown below:$(I)$ The double bond is between $C$ and the top oxygen atom.$(II)$ The double bond is between $C$ and the right oxygen atom.$(III)$ The double bond is between $C$ and the left oxygen atom.Thus,the total number of resonance structures is $3$.

The number of possible resonance structures for $CO_3^{2-}$ is
