Strategies

On completion of this course, the students will be able to-

CO61: compare the properties of first transition series (3d) with the second (4d) and third transition series(5d).

CO62: explain the various properties of f-block elements and differentiate between lanthanides and actinides as well as d and f-block elements.

CO63: describe the basic concepts of co-ordination chemistry, recognize isomerism in complexes, determine effective atomic number, (EAN), IUPAC name of coordination compounds, distinguish the structure of different types of complex on the basis of valence bond theory.

CO64: compare various theory of acids and bases and predict the strength of acids and bases.

CO65: classify various types of solvents and differentiate between sum non-aqueous solvents based on their properties and label different types of reaction of non-aqueous solvents.
