1.5 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 Potassium sulphate $\rightarrow$ Ionic solid Tin $\rightarrow$ Metallic solid Benzene $\rightarrow$ Molecular (non-polar) solid Urea $\rightarrow$ Polar molecular solid Ammonia $\rightarrow$ Polar molecular solid Water $\rightarrow$ Hydrogen bonded molecular solid Zinc sulphide $\rightarrow$ Ionic solid Graphite $\rightarrow$ Covalent or network solid Rubidium $\rightarrow$ Metallic solid Argon $\rightarrow$ Non-polar molecular solid Silicon carbide $\rightarrow$ Covalent or network solidShow Answer
Answer The given properties are the properties of a covalent or network solid. Therefore, the given solid is a covalent or network solid. Examples of such solids include diamond (C) and quartz $\left(\mathrm{SiO}_{2}\right)$.Show Answer
Answer In ionic compounds, electricity is conducted by ions. In solid state, ions are held together by strong electrostatic forces and are not free to move about within the solid. Hence, ionic solids do not conduct electricity in solid state. However, in molten state or in solution form, the ions are free to move and can conduct electricity.Show Answer
Show Answer
Answer
Metallic solids are electrical conductors, malleable, and ductile.
