Question

Which statement regarding polymers is not correct?

A

Elastomers have polymer chains held together by weak intermolecular forces

B

Fibers possess high tensile strength

C

Thermoplastic polymers are capable of repeatedly softening and hardening on heating and cooling respectively

D

Thermosetting polymers are reusable

Step-by-Step Solution

Thermoplastic polymers are linear or slightly long chain molecules capable of repeatedly softening and hardening on cooling. Thermosetting polymers are cross-linked or heavily branched molecules, which on heating undergo extensive cross-linking in moulds and again become infusible. These cannot be reused. Elastomers have polymer chains held together by weak intermolecular forces. Fibres possess high tensile strength.

Exam Context & Concepts Covered

This question aligns with the NEET CHEMISTRY syllabus, specifically targeting concepts from General. Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations. Solving conceptually related problems will help you understand the nuances of these concepts and improve your problem-solving speed.
