(a) (24 points) Below is shown a model MO diagram describing a generic heteronuclear
where the “heavy-atom” orbital energies are assumed, as shown.
For the transient diatomic NF fill in the MO diagram; make sure that you identify which
atom (N or F) corresponds to the
species in the diagram, and that you place the
valence electrons both into AO’s and MO’s as appropriate. Based on your MO diagram,
also answer the questions below.
i. Identify the bond order in the NF molecule.
ii. The bond length in NF is measured to be 135 pm; in the ion NF
, it is found to be
124 pm. Does your MO diagram provide an explanation for the shortening of the
NF bond when an electron is lost? Explain.
