Arrange the following polymers in an increasing order of intermolecular forces; fibre, plastic, elastomer.

Options

  1. AElastomer < Fibre < Plastic
  2. BElastomer < Plastic < Fibre
  3. CPlastic < Elastomer < Fibore
  4. DFibre < Elastomer < Plastic

Correct answer

B. Elastomer < Plastic < Fibre

Step-by-step solution

Elastomers or rubbers have the weakest intermolecular forces of attraction followed by plastics while fibres have the strongest forces of attraction. Thus, the increasing intermolecular forces of attraction follows the order elastomer < plastic < fibre.
