b) Covalent bond: Polarizing power and polarizability, ionic potential, Fajan’s rule. Lewis structures, formal charge. Valence Bond Theory. Directional character of covalent bonds,hybridizations, equivalent and non- equivalent hybrid orbitals, Bent’s rule,Dipole moments, VSEPR theory, shapes of molecules and ions containing lonepairs and bond pairs (examples from main groups chemistry) and multiple bonding (sand π bond approach). MO diagrams of B₂, C₂, N₂ and O₂ molecules and their simple applications.
