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 a splitting of energy of the 3d orbitals

b) eg orbitals are more stable than t2 orbitals

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

d) The high-spin case gives maximum unpaired electrons

e) For a given ligand, Co3+ causes a greater increase in the crystal field splitting energy than does Co2+
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
