7. Construct an MO diagram for lithium hydride, (LiH). Clearly show the relative orbital energies and determine the bond order. (a) The experimental dissociating energy is 245 kJ per mole. Compare this value to those of Li and H (table in lecture 5). Is it reasonable? (b) Which atoms Li or H bears a partial negative charge in this compound? 8. (a) Explain why the first ionization energy of N is greater than N (use MO diagram of N and Lewis model for N to explain). (b) Predict which is more favorable (i.e more positive): The first electron affinity of N or that of N. Defend your answer.
