Write the order of intermolecular forces in neoprene, nylon 6 and PVC.

Answer»

Solution :Increasing ORDER of intermolecular FORCES is : `"neoprene"lt"polyvinylchloride"lt"nylon"6`. Neoprene rubber is cis-1,4-polychloroprene. It has very weak van der Waals forces.
Van der Waals forces are relatively stronger in polyvinylchloride, because of the presence of halogen atoms. Nylon 6 is a polyamide and hence van der Waals forces are EVEN stronger.
