Textbook Question
Chapter 9, Problem 24PS
When potassium and oxygen react, one of the products obtained is potassium superoxide, KO2. The anion in this compound is the superoxide ion. O2–. Write the electron configuration for this ion in molecular orbital terms, and then compare it with the electron configuration of the O2 molecule with respect to the following criteria:
- (a) magnetic character
- (b) net number of σ and π bonds
- (c) bond order
- (d) oxygen–oxygen bond length
A closed-circuit breathing apparatus that generates its own oxygen. One source of oxygen is potassium superoxide (KO2). Both carbon dioxide and moisture exhaled by the wearer into the breathing tube react with the KO2 to generate oxygen.
