Problem
Sulfur dioxide, SO2, can be depicted by two Lewis structures.
• Structure A: O=S=O (each S–O bond is a double bond).
• Structure B: :O–S=O (one S–O single bond; the single-bonded O atom has three lone pairs).
Calculate the formal charge on the sulfur atom in each structure and indicate which structure is more favorable on the basis of your results.
