2. i. Draw the valence-level molecular orbital diagram for diatomic \( \mathrm{BN} \). Be sure to label each atomic and molecular orbital in the diagram. ii. Write the valence electron configuration for this molecule. iii. Determine the bond order of this molecule. 3. Using above BN molecular orbital diagram as a guide, draw a possible band diagram for the solid semiconductor BN. Label each band with the type(s) of molecular orbitals in contains. [Hint: use your understanding of semiconductor band diagrams to decide which MO's constitute a band and where any energy gaps should fall. Your diagram should have more than two bands. 4. How does the stability of \( \mathrm{BN}^{+} \)and \( \mathrm{BN}^{*} \) vary with respect to \( \mathrm{BN} \) ? 5. Compare the bonding in \( \mathrm{O}_{2}, \mathrm{O}_{2}{ }^{*}, \mathrm{O}_{2}{ }^{2-} \) and using valence -level molecular orbital diagrams. Include Lewis structures, bond lengths, and bond strengths in your answer.
