Oxygen homework

1. Superoxide ion, O₂^-, is an extremely reactive ion derived from O₂ in living systems.

(a) Is superoxide a radical? Explain.

(b) Use your molecular orbital diagram constructed using O p orbitals to explain which species, O₂^- or O₂^2- has the stronger oxygen-oxygen bond. Give the bond order for each to help make your case.

2. Why does oxygen the element exist as small molecules like O₂ vs large extended molecules like S₈? Draw Lewis dot structures for each molecule and refer to these to make your case.

3. Which is the more polar molecule: SO₂ or O₃? Draw clear dot and VSEPR sketches for each and refer to these to make your case.

4. Problems 11.8, 11.16, 11.32 from the text.
