This question shows how molecular orbital (MO) theory can be used to understand the chemical
properties of elemental oxygen O₂ and its anionic derivative superoxide Oz.
a)
Draw the MO energy diagram for both O2 and O2. Clearly label your diagram with atomic orbital names
and molecular orbital symmetry labels and include electrons.
Draw the Lewis structure of O2. How does the MO description of O2 differ from the Lewis structure, and
how does this difference relate to the high reactivity and magnetic properties of oxygen?
) Use the MO diagram in (a) to explain the difference in bond length and bond energy between superoxide
ion (Oz, 135 pm, 360 kJ/mol) and oxygen (O2, 120.8 pm, 494 kJ/mol).
