Question

The polymer having strongest intermolecular forces is (1) fibres (2) elastomer (3) thermoplastic (4) thermosetting polymer

Answer 1

Hey mate!

Here's your answer!!

Option (d) Thermosetting polymers is the correct answer.

Explanation ➡ Thermosetting polymers are cross linked or heavily branched molecules which on hetaing undergo extensive cross linking in moulds and again become fusible.These have strongest intermolecular forces.Examples:-bakelite,urea-formaldehyde resins etc.

Hope it helps you!

Answer 2

Answer:  (4) thermosetting polymer

Explanation:

1) Fibre : Polymers which are more long than wide. They are held be weak forces. Example: rayon.

2) Elastomer: Polymers which have have elastic properties and can be deformed on applying pressure and that means they are held by weak forces. Example: rubber

3) thermoplastic: polymers which change their shape on applying heat and thus mean they are held by weak forces. Example: polythene.

4) Thermosetting polymer: polymers which do not change their shape on applying heat and thus mean they are held by strong forces. Example: bakelite which is used in making electrical switches.
