b) Experimentally, it is found that the value of Ao varies with the chemical nature of the ligand
according to the spectrochemical series:
I < Br¯ < Cl¯ < SCN¯ <F¯ < OH¯ < RCO, < H2O ~ RS¯ < NH3 < CN¯ < CO,
i.e., Ao is the smallest for I- and the largest for CO. Based on this information, draw an energy
level diagram showing the configuration of the d electrons on the metal ion in [Cr(F)6]³- and
[Cr(CO)6]3+. The electron configuration of Cr is: [Ar] 3d% 4s'.
