1. Find the point group for the following species: XeO3, hexacarbonylvanadium(0), and tris(2,2'-bipyridine)ruthenium(II) ion.
2. Find the LFSE in terms of Dq and P and the magnetic moment in terms of Bohr-magnetons for: fac-tribromotrichloroferrate(II) ion, hexacyanoferrate(III) ion, bis(η4-1,5-cyclooctadiene)nickel(0).
3. Consider the reactions:
[MF6]4–(aq) + 6 OH–(aq) → [M(OH)6]4–(aq) + 6 F–(aq) β is large
[M(H2O)6]2+(aq) + 6 OH–(aq) → [M(OH)6]4–(aq) + 6 H2O(l) β is small
Place hydroxide in the spectrochemical series and explain your reasoning.
4. Use the EAN rule to predict the stability of the following: trans-dichlorotetrakis(triphenylphosphine)nickel(II), chlorotris(triphenylphosphine)rhodium(I), [PtCl3(CH2=CH2)]–.
5. 10Dq is found to be 17400 cm–1 for [Cr(H2O)6]3+. a) Predict λmax in units of nm for the lowest energy d-d transition. b) Will this wavelength be longer, shorter, or the same if all of the water ligands are substituted with fluoride? Explain.
