Draw Lewis structures for the following molecules. Which molecule would you expect to have exactly 1 double bond? a.) Carbonate ion, CO₃²⁻ b.) Ethane, C₂H₆ c.) Ammonia, NH₃ d.) Carbon Monoxide, CO
a.) Carbonate ion, CO₃²⁻
- Carbonate ion has exactly 1 double bond as represented in the Lewis structure.

b.) Ethane, C₂H₆
- Ethane does not have any double bonds in its Lewis structure.

c.) Ammonia, NH₃
- Ammonia does not have any double bonds in its Lewis structure.

d.) Carbon Monoxide, CO
- Carbon Monoxide has exactly 1 double bond as represented in the Lewis structure.
