The orbital potential energies for the 4s and 4p of Br are
-18.65 ev and -12.49ev, respectively. Recall that the H 1s is
-13.61ev. The MO diagram for HBr is not exactly the same as HF.
Draw the MO diagram for HBr, including energy levels, each orbitals
shape, each orbitals character (meaning what atomic orbitals
contribute to each M.O. and how much), symmetry labels (e.g. and
, * and *), indicate the HOMO and LUMO, the bond order (show...
