Arrange the following polymers in an increasing order of intermolecular forces; fibre, plastic, elastomer.
A
Elastomer < Fibre < Plastic
B
Elastomer < Plastic < Fibre
C
Plastic < Elastomer < Fibre
D
Fibre < Elastomer < Plastic
Answer
Elastomer < Plastic < Fibre
Explanation
Solution
Elastomers or rubbers have the weakest intermolecular forces of attractions followed by plastics while fibres have the strongest forces of attractions. Thus, the increasing intermolecular forces of attractions follows the order :
Elastomer < Plastic < fibre.
