1.	Classify the following solids in different categories based on the nature of intermolecular forces operating in them : Potassium sulphate, tin, benzene, urea, ammonia, water, zinc sulphide, graphite, rubidium, argon, silicon carbide.
Answer» Solution :Potassium sulphate = Ionic, Tin=Metallic, Benzene=Molecular (non-polar). Urea=Molecular (Polar), Ammonia= Molecular (Hydrogen bonded), Water=Molecular (Hydrogen bonded), Zinc sulphide = ionic, Graphite = Covalent or NETWORK, Rubidium = Metallic. ARGON = Molecular (Non-polar), Silicon carbide = Covalent or Network
