(Theory: 2 credits)

Unit 1: Atomic Structure:

Review of Bohr’s theory and its limitations, dual behaviour of matter and radiation, de-Broglie’s relation, Heisenberg Uncertainty principle. Hydrogen atoms spectra. Need of a new approach to Atomic Structure.

Significance of quantum numbers, orbital angular momentum and quantum numbers mi and ms. Shapes of s, p and d atomic orbitals, nodal planes. Discovery of spin, spin quantum number(s) and magnetic spin quantum number (ms).

Rules for filling electrons in various orbitals, Electronic configurations of the atoms. Stability of half-filled and completely filled orbitals, concept of exchange energy. Relative energies of atomic orbitals, Anomalous electronic configuration, Hund’s, Pauli’s and Aufbau’s principle.

Unit 2: Chemical Bonding and Molecular Structure

Ionic Bonding: General characteristics of ionic bonding. Energy considerations in ionic bonding, lattice energy and solvation energy and their importance in the context of stability and solubility of ionic compounds. Statements of Born-Lande equation for calculation

of lattice energy, Born-Haber cycle and its applications, polarizing power and polarizability. Fajan’s rules, ionic character in covalent compounds, bond moment, dipole moment and percentage ionic character.

Covalent bonding : VB Approach: Shapes of some inorganic molecules and ions on the basic of VSEPR and hybridization with suitable examples of linear, trigonal planar, square planar, tetrahdral, trigonal bipyramidal and octahedral arrangements. Concept of resonance and resonating structures in various inorganic and organic compounds.
