(a) Using only the valence atomic orbitals of a hydrogenatom and a fluorine atom, and following the model ofFigure 9.46, how many MOs would you expect for the HFmolecule? (b) How many of the MOs from part (a) would beoccupied by electrons? (c) It turns out that the difference inenergies between the valence atomic orbitals of H and F aresufficiently different that we can neglect the interaction ofthe 1s orbital of hydrogen with the 2s orbital of fluorine.The 1s orbital of hydrogen will mix only with one 2p orbitalof fluorine. Draw pictures showing the proper orientationof all three 2p orbitals on F interacting with a 1s orbitalon H. Which of the 2p orbitals can actually make a bondwith a 1s orbital, assuming that the atoms lie on the z-axis?(d) In the most accepted picture of HF, all the other atomicorbitals on fluorine move over at the same energy into themolecular orbital energy-level diagram for HF. These arecalled “nonbonding orbitals.” Sketch the energy-level diagramfor HF using…
a.) Give the bond order of Li2 ,Be2 ,C2 b.) Give the ground state electron configurations ofCO,NO ,CN- .The gerade and ungerade designation is technically not appropriate for heteronuclear diatomics, but rather use the "*" after S or P to represent antibonding. Still, S would stand for σ. Let P represent a pair of π MO's. Enclose each MO in parenthesis followed by the number of electrons in that MO, e.g., the entry (1S*)2 would represent 1σ* 2.

The orbital potential energies for the 4s and 4p of Br are -18.65 ev and -12.49 ev, respectively. Recall that the H 1s is -13.61 ev. The MO diagrams 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 indicate the HOMO and LUMO, the bond order (show your work), whether the molecule is paramagnetic or diamagnetic. Compare and contrast the MO diagrams of HF and HBr.
