Question -
Answer -
(i) Nylon 6, 6, Buna-S, Polythene.
(ii) Nylon 6, Neoprene, Polyvinyl chloride.
Answer
Different types of polymers have different intermolecularforces of attraction. Elastomers or rubbers have the weakest while fibres havethe strongest intermolecular forces of attraction. Plastics have intermediateintermolecular forces of attraction. Hence, the increasing order of theintermolecular forces of the given polymers is as follows:
(i) Buna − S < polythene < Nylon 6, 6
(ii) Neoprene < polyvinyl chloride < Nylon 6
