How many equivalent resonance forms can be drawn for CO₃^2-? (Carbon is the central atom.) A)1 B)2 C)3 D)4 E)0

Question

Quizplus · Accepted Answer

The carbonate ion (CO₃²⁻) has three equivalent resonance forms. Each form has one of the oxygen atoms double-bonded to the carbon, while the other two oxygen atoms have single bonds and carry a negative charge. The double bond can be placed between the carbon and any of the three oxygen atoms, resulting in three equivalent structures.
