To determine which molecule has one unpaired electron, we can analyze each option step by step using molecular orbital theory. ### Step-by-Step Solution: 1. **Identify the Total Electrons in Each Molecule:** - For **O2**: Each oxygen atom contributes 8 electrons (total 16 electrons). - For **CN-**: Carbon (6) + Nitrogen (7) + 1 (negative charge) = 14 electrons. - For **NO**: Nitrogen (7) + Oxygen (8) = 15 electrons. ...
