Classification of crystalline solids.
1. Molecular solids: The forces operating between molecules are dispersion or London forces, dipole – dipole interactions, hydrogen bounding e.g. , HCl, ice etc.
2. Ionic solids: The intermolecular forces are coulomibic or electrostatic forces, e.g. NaCl, MgO etc.
3. Metallic solids: The forces operating is metallic bonding e.g. Fe, Cu, Ag etc.
4. Covalent or network solids: The attractive forces are covalent bonding e.g. Diamond, Quartz etc.
