Final answer:
The Lewis structure for carbonate (CO₃²⁻) has multiple resonance forms, making it exhibit resonance.
Step-by-step explanation:
The Lewis structure for carbonate (CO3²⁻) can be represented with a central carbon atom bonded to three oxygen atoms. One oxygen atom forms a double bond with the carbon, while the other two form single bonds. The Lewis structure can be drawn with the double bond in different positions, resulting in three resonance structures.
The molecule exhibits resonance because it has multiple possible Lewis structures that differ only in the arrangement of electrons. These resonance structures are all valid representations of the carbonate ion, and the actual structure is an average of the resonance forms.
Therefore, the answer is a. Yes.
