Question

To determine the number of resonance structures that can be drawn for a molecule, we need to identify the different ways in which the electrons can be delocalized. In the case of CO₃^2-, we have a central carbon atom with a double bond to oxygen and a single bond to sulfur. The possible resonance structures can be drawn by moving the double bond around between the carbon and oxygen atoms, while keeping the sulfur atom and the lone pair of electrons on the oxygen in the same position. This gives us three possible resonance structures, as shown below: O=S-C=S O=C-S O=S=C | | | S-P S-P S-P Therefore, the answer is C) 3.
