MCQs on Types of Bonding and Forces in Solid

In solids, molecules are tightly packed and only oscillate about their fixed positions. Nature of bonding and forces that hold particles (atom, molecules, ions, etc.) together in a solid explain its properties. Solids can be classified as metallic, covalent, ionic or molecular, based on the types of intermolecular forces present in them.
