Final exam review

As in the previous post, (en) is bidentate, so the compound in problem 10 is not actually real (we can have a maximum coordination number of 6, corresponding to an octahedral shape - the coordination number here is 9).  But for the purpose of naming, we can still name the compound.

Crystal field theory

Please note that the compound in problems 2 and 3 is not actually real.  The coordination number for the compound as written is 8, which is not possible.  This is because (en) - ethylenediamine is a bidentate ligand.  If (en) were monodentate, it would be octahedral as in problem 3.  This is not actually correct, but the example can still be useful.

MO diagrams for 2nd row diatomics

This picture shows the MO diagrams for the 2nd row diatomic (homonuclear) molecules.  Note that the relative energies change for the MOs as you change the identity of the molecule.  This picture also shows where the sp mixing effectively "turns off".
