Question

Arrange the following polymers in the increasing order of their intermolecular forces:

Polystyrene, Terylene, Buna-S

Answer 1

Elastomers of rubbers have the weakest intermolecular forces of attraction, while fibres have the strongest intermolecular forces of attraction. Plastics have intermdiate forces of attraction.

The increasing order of intermolecular forces of attraction of the given polymers is as follows:

Terylene > Polystyrene > Buna-S
