1 sketch the unoccupied mo of the h2 ion does this orbital

Question

1) Sketch the unoccupied MO of the H₂⁺ ion. Does this orbital have a node?  If yes, sketch and describe the surface.

2) How does the energy of the s-bonding MO of H₂⁺compare to that of the 1s orbital of hydrogen ?

3) Would you expect H₂⁺ to act as an oxidant or as a reducing agent toward the H₂^-  ion in a chemical reaction? Explain

4) Sketch the highest occupied MO of He₂⁺. Does this orbital have a node? if yes, sketch and describe the surface.

5) Should the He₂⁺ion have p-MOs. Explain

6) Would you expect He₂⁺to act as an oxidant or as a reducing agent in a chemical reaction? Explain.

7) For boron trifluoride, draw a correct lewis structure of BF₃ consistent with the MO description of bonding in the molecule.  How many molecular orbitals support p-bonding in BF₃? How many atomic orbitals contribute to the p and p* MOs of BF_3?
