Concept of Acids and Bases: Acidity, basicity, models of acid-base chemistry (Arrhenius, Bronsted-Lowry, Lewis and Pearson HSAB), concepts of HSAB and Lewis model in correlation with frontier orbitals, examples of reaction governed by HSAB principle, hardness scale, concept
of super acids and bases.
Introduction to Crystal Field theory: CFT basic postulates, octahedral, tetrahedral, square-planar, square-pyramidal, trigonal bipyramidal crystal field, Ligand effect and CFSE, influence of CFSE on stability, drawbacks of CFT, inorganic nomenclature, isomerism, octahedral and tetrahedral holes, spinel structures and influence of CFSE.
Bonding-II: Introduction to Symmetry, symmetry and its elements, symmetry operations, combination of symmetry operations, finding point group, improper axis of rotation vs. chirality, properties of point group, expressing symmetry operations in matrices, Mullikens symbols of
relevance, use of character table of C 2v , C 3v , C 2h , Use of reducible and irreducible representations and Mullikens symbols, overlap and symmetry, use of symmetry to construct molecular orbitals, recapitulation of N 2 , O 2 and CO orbitals of a molecule in a point group. Construction of MO diagram of H 2 O, NH 3 , BH 3 /BF 3 comparison use of AO energies and nodes to guess qualitative ordering of orbitals, comparison of properties using MO diagram.
