Question

Which of the following are true for the Crystal Field Model of an octahedral complex ion? Consider ions to be from first-row transition metals.



a) The ligands cause all 3d orbitals to have equal energy

b) e orbitals are less stable than t2 orbitals

c) A large crystal field splitting energy results in a paramagnetic complex

d) The low--spin case gives minimum unpaired electrons

e) For a given ligand, Mn3+ causes a greater increase in the crystal field splitting energy than does Mn2+
think about the amount of coulombic attraction between the metal ion and the electrons on the ligands
and the closer the ligands, the more interaction there is with the d orbitals on the metal ion

f) Cl- causes a greater increase in the crystal field splitting enery than does H2O

g) The splitting of energy (E) of 3d orbitals occurs in the metal ion
