Consider the [VII(H2O)6]2+ ion. Explain why there are this number of bands and not more or less, which might be expected (i.e., which sets of electronic transitions give rise to these bands)

has a crystal field splitting energy, o, of 2.60102 kJ/mol. What is the wavelength responsible for this energy?

Platinum(II) forms many complexes, among them those with the following ligands. Give the formula and charge of each complex. (a) two ammonia molecules and one oxalate ion (C2O42-) (b) two ammonia molecules, one thiocyanate ion (SCN-), and one bromide ion (c) one ethylenediamine molecule and two nitrite ions

Draw the octahedral crystal field d orbital splitting diagrams for [Fe(OH2)6] 2+ and [Fe(CN)6] 3. Indicate if the diagrams are high spin and low spin. give the names of the d-orbitals (dxz, dxy, dzy, dz2, dx2 - y2) label the appropriate orbital sets eg* and t2g and show how the electrons populate the diagram. (Hint: Pairing energy for 3d orbitals Fe 2+ = 29875 cm-1, Fe 3+ = 19150 cm-1; delta OH for Fe(OH2)6]2+ = 14300 cm-1 and delta OH for [Fe(CN)6]3 - is 35000 cm-1
