Assertion : The correct order of increasing molecular forces in the given polymres is : Buna-S, Polthene, Nylon -6,6
Reason : The properties of polymers depends upon the molecular forces.

A

If both assertion and reason are true and reason is the correct explanation of assertion .

B

If both assertion and reason are true but reason is not the correct explanation of assertion .

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
B
Elastomers ( buna-S) have weakest intermolecular forces .
Fibres ( nylon -6,6) have strong intermolecular forces. Thermoplastic polymers ( polythene ) have intermolecular forces intermediate between elastomers and fibres.
