- explain different types of bonds formed by the atoms. l differentiate between ionic and covalent bonds.
- draw the shapes and geometries of various molecules by using VSEPR Theory.
- understand the difference between valence band theory and molecular orbital theory.
- explain the hybridization and its relation to the shape of molecules.
- write the electronic configuration in molecular orbitals for simple diatomic molecules.
- calculate the bond order on the basis of electron distribution in various molecular orbitals.
- predict the bond strength and magnetic properties of molecules on the basis of MO theory.
- explain the effect of hydrogen bonding on the properties of molecules.
