Arrange the following polymers in increasing order of their intermolecular forces. Nylon-6,6, buna-S, polythene, neoprene (JIPMER 2018)

The increasing order of inter molecular forces in different polymers is elastomers < plastics < fibres. So, in order to solve such problem, first classify the given polymer into the above classes and then arrange them in increasing order of forces. Neoprene (synthetic rubber) is an elastomer, buna-S is also an elastomer, polythene is plastic and nylon-6, 6 is a fibre. So, the increasing order of intermolecular forces of the given polymer is : Neoprene < buna-S < polythene < nylon-6, 6
