a) Trialkylphosphine and ammonia are both strong-field ligands. However, experimental data show that in their complexes PR3 ligands cause higher splitting energy(A.) than NH3 although the central metal atoms are in the same VA group. How can you explain these results? b) Give a comparison on the formation constants of the following substitution reactions and give an explanation. (dmpe: 1,2-Bis(dimethylphosphino) ethane) [Cd(H2O)«]³*(aq) +2 PR3 → [Cd(PR3)2(H2O)«]³*(aq) + 2H2O Ki [Cd(H;O)«J**(aq) + dmpe → [Cd(dmpe)(H2O)4]³*(aq) + 2H2O KI

Answer the following questions for the transition metal complex Mn(OH)6. Using sigma - only considerations: a) Draw the 5 d orbitals associated with the transition metal center and state whether each one will overlap (strongly, weakly, or not at all) with the ligands (assume sigma bonding only). b) Using your answer for (a), draw and label the energy levels of the d orbitals (i.e. the d orbital splitting diagram). c) Fill in the correct number of electrons.
