The students will be able to – CO97: describe the important postulates of CFT, construct splitting diagrams of d-orbitals for different geometries and calculate CFSE of different complexes. CO98: apply Jahn Teller Theorem to explain the crystal field splitting in square planar complexes, differentiate between high spin and low spin complexes and explain the colour of complexes. CO99: differentiate between different types of magnetic behaviour and interpret magnetic moments for different complexes. CO100: describe L-S coupling and compute ground state terms, employ selection rules, sketch Orgel diagrams and discuss electronic spectrum of Ti+3. CO101: differentiate between different types of errors and distinguish between accuracy and precision. Calculate various types of deviations to express precision. CO102:discuss principle, requirements and methods involved in different gravimetric analysis and identify various types of reagents used in gravimetric analysis. |
