Course Synopsis

The first part of the course comprises of the study of anomalous behaviour of certain elements in a period table. The use of p and d block orbitals would be discussed with respect to anomalous behaviour of these elements. The second part of yhe course consists of study of reaction rates of inorganic reactions. Both square planar and octahedral metal complexes will be studied and their reaction mechanism will be discussed.

Course Learning Outcomes

At the end of the course, students should have understood the anomalies present in periodic table. They would have a deep understanding of the reaction rates and mechanism in square planar and octahedral metal complexes.
