Question

4. Compare the magnetic properties of [Fe(H2O)6]2+ and[Fe(CN)6]4-.

5. What change in magnetic properties (if any) can be expected whenNO 2-
ligands in an octahedral complex are replaced by Cl- ligands in ad6 complex?

6. Draw the orbital splitting diagram for the following complex andgive its
electron configuration: tetrahedral CoCl42-.

7. The complex ion PdCl42- is diamagnetic. Propose a structure forPdCl42-.

8. Explain the following differences in color:

A. [Cr(H2O)6]Cl3 is violet, whereas [Cr(NH3)6]Cl3 is
yellow.

B. [Co(H2O)6]2+ is pink, whereas tetrahedral
[CoCl4]2- is blue.

C. One of the following solids is yellow, and the other is
green: Fe(NO3)2·6H2O versus K4[Fe(CN)6·3H2O].
Indicate which is which and explain your reasoning.
