1. For each of the following complexes: a) low spin [Rh(NH3)6]3 + b) [Ti(OH2)6]3+ c) high spin [Fe(OH2)6]3 + i. What is the oxidation number of the center of the metal? ii. Determine the electron configuration of the d- orbital of the metal? iii. Write the electron configuration for that. orbital d

Experiments show that K4[Cr(CN)6] is paramagnetic and has two unpaired electrons. The related complex K4[Cr(SCN)6] is paramagnetic and has four unpaired electrons. Account for the magnetism of each compound using the ligand field model. Predict where the SCN ion occurs in the spectro-chemical series relative to CN.

Classify each ligand as monodentate, bidentate, and so on. (a) (CH3)3P (b) H2N(CH2)2NH(CH2)2NH2 (c) H2O

Give the number of unpaired electrons in octahedral complexes with strong-field ligands for (a) Rh3+ (b) Mn3+ (c) Ag+ (d) Pt4+ (e) Au3+
