A 3.03-g petroleum specimen was decomposed by wet ashing and subsequently diluted to 500 mL in a volumetric flask. Cobalt was determined by treating 25.00-mL aliquots of this diluted solution as follows: Assume that the Co(II)-ligand chelate obeys Beer’s law, and calculate the percentage of cobalt in the original sample.
Explain in detail π backbonding using the molecular orbitals of CO and a d-transition metal. How does this influence Infrared Spectroscopy and explain how the bond order for the C-O bond changes and how the bond order for the metal-ligand bond changes. Provide pictures and explanations.

Werner prepared two compounds by heating a solution of PtCl₂ with triethyl phosphine, P(C₂H₅)₃, which is an excellent ligand for Pt. The two compounds gave the same analysis: Pt,38.8%; Cl, 14.1%; C, 28.7%; P, 12.4%; and H, 6.02%. Writeformulas, structures, and systematic names for the two isomers
Many transition metal complexes are said to follow the “18-electron rule,” meaning they form particularly stable complexes when the metal + ligand electrons contributing to the MOs add up to a total of 18 electrons. a. Use the full MO diagram for an octahedral metal complex with pi-acidic ligands we derived in class to justify why 18-electrons might be particularly stable. b. Use the 18-electron rule to predict which 1st row transition metal would be most likely to form an octahedral M(CO)6 (Note: there is no charge; the metal retains all its electrons.) c. Qualitatively, how would you expect the CO bond to change when it forms this complex? Would it be stronger, weaker, or the same compared to free CO? (Hint: think about what a ? −???? means and what the orbital does from the perspective of the M–CO interaction as well as the C– O interaction).
Nickelocene is an example of another meallocene. It is paramagnetic with two unpaired electrons. Rationalise this and suggest a bonding scheme, which accounts for it. Do start with the symmetry and the molecular orbitals of the Cp- ligand.
The anticancer drug cisplatin, cis-[Pt(NH3)2Cl2] (see Figs. 8.12b and 8.33),can be prepared from K2PtCl6 via reduction with N2H4 (hydrazine), givingK2PtCl4, followed by replacement of two chloride ion ligands with ammonia. Give systematic names to the three platinum complexes referred to inthis statement.
In general, would you expect EDTA4- to coordinate to transition metal ions more or less strongly than ethylenediamine does? Justify your answer with a reason other than the different charges on the two ligands.
Regarding the formation of the tetracyanetoniquelate (II) complex answer:a.Demonstrates hybridization according to the valence bond theory and indicate itsgeometry.b.
