Polymorphism can exist in any crystalline material, not just molecular solids. True or false? Explain how?
Crystalline solids are those where a long-range order is present in the arrangement of constituent particles. While in amorphous solids the constituent particles are arranged in short-range order. Crystalline solids are of four types, ionic, metallic, covalent, and molecular. Polymorphism is the property exhibited by crystalline materials. It is the property in which a chemical composition crystallizes in different forms. That is, a particular chemical composition exists in more than one crystalline structure. These structures have identical chemical compositions but differ in the arrangement of molecules in the crystal lattice. Therefore they do differ in some physical and chemical properties.
