The answers no need to be long (cause I have to memorize it for tomorrow exam), just the main points.

1.

a.Cu(TPP) is active in UV-Vis AND why? EXPLAIN YOUR REASON.

If you replace Cu2+ with Zn2+ and you have Zn(TPP), what will happen to the UV-vis spectra? EXPLAIN your answer

b. Is Wilkinson`s catalyst [RhCl(PPh3)3 ] active in UV-Vis AND why? EXPLAIN YOUR REASON.

Where the UV-vis spectra of the Wilkinson`s catalyst [RhCl(PPh3)3 ] will be shifted if you replace Cl- with SCN in its crystal structure?

2.

Identify the weakest coordinating ligand in the following complexes. Clearly explain your reasoning.

A ) HRh(CO)(PMe3)3

B ) [Pt( NH3)2Cl2]

C ) Wilkinson`s catalyst [RhCl(PPh3)3 ]

D ) Vaska`s Complex, IrCl(CO)[P(C6H5)3]2
