Question

Match the following polymers with their applications:

• A. A−III,B −V,C −I,D−II
• B. A−I,B −II,C −IV,D−III
• C. A−II,B −IV,C −I,D−III
• D. A−II,B −IV,C −V,D−I

Hint:

Different polymers have unique mechanical and chemical properties that determine their industrial applications.

Answer 1

The Correct Option is C

Step 1: Identifying Each Polymer - Polytetrafluoroethylene (PTFE) \( \text{[--CH}_2\text{--CF}_2\text{--]}_n \) → Used in gaskets, as it is resistant to chemicals and heat. - Polyacrylonitrile (PAN) \( \text{[--CH}_2\text{--CH--]}_n \text{CN} \) → Used in commercial fibres like synthetic textiles. - Epoxy resins \( \text{[--OCH}_2\text{CH}_2\text{O--]}_n \text{--C--} \text{--O--} \) → Used in safety helmets for their impact resistance. - Polyurethane \( \text{[--NHCONHCH}_2\text{--]}_n \) → Used in laminated sheets due to flexibility and strength. Conclusion Thus, the correct answer is: \[ A-II, B-IV, C-I, D-III \]
