QUESTION 2: You have prepared the novel coordination compound ammonium dichlorodioxalatovanadate(?): (NH4)3[VCl₂(O₂CCO₂)₂]. a) What is the oxidation state of vanadium in the coordination compound? b) How many d-electrons are present in vanadium in this compound? c) Draw 2 isomers of the geometrically octahedral complex anion and determine their point groups. You must use dashes and wedges correctly to indicate the ligand positions. You must show all atoms including the ligand atoms. i. Isomer 1 (octahedral): trans-[VCl₂(O₂CCO₂)2]³- 1. Draw the 3-dimensional structure of the trans-[VCl₂(O₂CCO₂)2]³ complex.

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)
