Pre requisite: An elaborate idea of periodic table and electronic configurations

 

Introduction, electronic configuration, characteristic properties of d-block elements– metallic character, variable oxidation states and their stability, density, melting point and boiling point., catalytic properties, ionization energies, magnetic properties and its origin, measurement of magnetic moments, colour, complexation tendencies.

 

 

5.00
Unit II: 
Chemistry of Elements of Second and Third Transition Series

Electronic configuration, general characteristics, comparison of the elements of first transition series with second and third transition series with special reference to magnetic property, spectral property, stability of variable oxidation states and stereochemistry, ionic radii, complexation tendencies; metal-metal bonding and cluster compounds (elementary approach)

 

6.00
Unit III: 
Basic Concepts of Coordination Chemistry

Introduction, Werner’s coordination theory, concept of effective atomic number (EAN concept), classification of ligands, chelation, polynuclear complexes, IUPAC nomenclature of coordination compounds and methods of preparation of octahedral complexes of Fe, Co, and Ni(with monodentate ligands only), structure and bonding.

 

6.00
Unit IV: 
Models and Stereochemistry

Isomerism in coordination compounds, structural isomerism and its types, stereochemistry of complexes of 4 and 6 coordination number, salient features of valence bond theory (VBT), structure of octahedral, tetrahedral and square planar complexes on the  basis  of VBT  and its limitations.                                       

 

7.00
Unit V: 
Chemistry of Inner-Transition Elements

Lanthanides: definition, position of lanthanides in the periodic table, separation of rare earth elements (solvent extraction and ion exchange method only), electronic configuration, physical properties, oxidation states, atomic and ionic radii, lanthanide contraction, causes and consequences of lanthanide contraction, magnetic and spectral properties;  comparison between d- and f- block elements.

Actinides: definition, position of actinides in the periodic table, electronic configuration,  general characteristics of actinides and their comparison with lanthanides with special reference to magnetic properties, spectral properties and oxidation states.
