CHEM 1 Advance Science Institute Questions
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
