Inorganic Chemistry III: Coordination Chemistry

(Theory)

 

 

 

CO67: Discuss the properties of 3d block elements and compare with that of 4d and 5d elements.

CO68: Explain the various properties of f-block elements and differentiate between

lanthanides and actinides as well as d and f-block elements.

CO69: Describe the basic concepts of co-ordination chemistry, recognize isomerism in complexes and

assign IUPAC name to the coordination compounds.

CO70: Explain the important postulates of VBT and CFT, construct splitting diagrams of d-orbitals for different

geometries and calculate CFSE of different complexes. 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.

CO71: Differentiate between bulk and trace elements, identify the importance of metal ions in biological

systems, describe the structure and functions of different metalloenzymes and explain the mechanism of

photosynthesis.

CO72: Contribute effectively in course-specific interaction.

Approach in teaching:

Interactive lectures, tutorials, group discussions and e-learning.

 

 

Learning activities for the students:

Peer learning, e-learning, problem solving through tutorials and group discussions.

 

Written examinations, assignments and quiz.
