1) 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...

Draw a labelled diagram showing the atomic orbitals for N and O on each side and the molecular orbitals for NO, in the middle. The diagram should clearly show: which atomic orbitals combine to form each molecular orbital, the relative position (increasing energy going up the page) of the molecular orbitals and the locations of electrons in the atomic orbitals and in the molecular orbitals. Use your diagram to determine the following: What is the bond order? Explain how you...
