Which of the following are true for the Crystal Fiekd Model of an octahedral complex ion? Cnsider ions to be?

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) Two of the 3d orbitals point directly at ligands

b) t2 orbitals are less stable than e orbitals

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

d) The low--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 ligands

i know d is false i cant seem to get the right answer tho

a) true
b) false
c) false
d) false
e) true
f) false
g) false
