Time 3 Hours. Full Marks 80
Answer any FIVE Questions.
All questions carry equal marks.
1. What do you understand by crystal field stabilization energy in complex What are the factors
which determine the crystal field stabilization energy.
2. What do you mean by splitting of d-orbital under the influence of Ligand. How does the dorbital
split in Tetrahedral crystal field theory
3. Discuss the labit and inert octahedral complex on the basis of C.F.T.
4. Explain the factors which affect the acid hydrolysis reactions in octahedral complex.
5. How does ionic radii of M vary from d 0 to d 10 system in the first transition system
due to crystal field.
S and P term do not split in crystal field but D and F term split, explain.
6. Discuss electronic spectra of d 1 and d 2 system in octahedral and tetrahedral electric
field.
Explain, by giving examples, John Tellor distortions.
7. What is meant by microstate What is the possible maximum number of possible microstates
for p² configuration Derive the possible Russel Saunder's microstate for p² according to
Hund's rule, arrange them increasing order of energy and identify the ground state term
symbol.
8. What are selection rules for d-d transition
Explain magnetic moment and magnetic susceptibility and establish relation between
them.
9. Why magnetic moment of first transition series metal complex often approaches the value
but same result do not obtain in the series.
10. Write notes on the following
Spectro-Chemical Series.
Electro Paramagnetic Resonance.
