The observed rate constant kobs for ligand substitution reactions at square planar platinum(II) complexes is a combination of the rate constants from competing pathways with (kı) and without (k2) solvent participation. The rate constant (k2) for the substitution of a chloride in trans-[Pt(py)2C12] by different ligands (Y) in methanol solvent at 30 °C and the nucleophilicity parameter (npi) of these ligands is given below:(c) when Y = MeOH=solvent; the rate of reaction is 0.00027 s-'. Use this data to calculate the nucleophilic discrimination factor (s) for the complex [Pt(py)2C12]. Show all of your working. (py = pyridine) In methanol solvent at 30 °C the nucleophilic discrimination factor (s) for[Pt(dien)(OH2)]* = 0.44. Using your value of s from part (i) would you expect [Pt(dien)(OH2)]2* to be generally more or less reactive towards ligand substitution? Explain your answer.dien=diethylenetriamine H2N(CH2)2NH(CH2)2NH2)
