What is an example of an antibonding orbitals practice problem?

Practice reading the MO diagram of #"HF"# below.

Inorganic Chemistry, Miessler et al.

From the diagram:

  1. Identify the antibonding molecular orbital.
  2. Identify the three nonbonding molecular orbitals.
  3. Identify the only bonding molecular orbital.
  4. Which orbitals correspond to fluorine's three lone pairs of electrons?
  5. What is the bond order? Does it make sense given the single bond in #"H"-"F"#?
  6. Why is there one #sigma# orbital by itself at the bottom? What does that suggest about the energies of the #2s# of #"F"# and the #1s# of #"H"#?
