Why oxygen molecules are considered to be paramagnetic?
1) The photoelectron spectrum for water has four bands, not including ionizations from the 1s electrons of oxygen. Three of the bands have vibrational fine structure. The fourth band, which is from the least energetic ionization, shows no such fine structure. Explain these results in terms of your MO scheme.
2) If we added two more electron pairs to the MO scheme for BeH2, this would describe the bonding in water if water were a linear molecule. Compare your MO scheme for bent water with this hypothetical scheme for linear water, and comment on why water is bent instead of linear.
The nature of the highest occupied molecular orbital (HOMO) is often used to rationalize the chemical
behavior of molecules. Draw the molecular orbital diagram for cyanide (CN–). Using the MO diagram
rationalize why H+ will bond to the C atom and not the N atom.
