Kinetics and mechanism of inorganic reactions
Classification of inorganic reactions (D, Id, A, Ia mechanisms), Rate law, stationary state approximation, role of water as solvent, inert and labile complexes.
Substitution reactions in octahedral complexes, Acid hydrolysis, Acid catalyzed aquation, anation reaction
Square planar complexes
Substitution reactions in square planar complexes, nucleophilic reactivity, trans effect, Mechanism of substitution, effect of leaving group
Oxidation reduction reactions of metal ions
Outer sphere mechanism, Inner sphere mechanism
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.
Substitution in octahedral and square planar complexes
Periodicity and rate of inorganic reactions
Periodic anomalies of non metals and post transition metals
Substitution reactions in octahedral complexes
