(i) Teflon
(ii) Starch
(iii) Terylene
(iv) Orlon
- A (i) and (ii)
- B (ii) and (iii)
- C (iii) and (iv)
- D (i) and (iv)
Answer & Solution
Correct Answer
(C) (iii) and (iv)
Step-by-step Solution
Detailed explanation
Among the given sets of polymer terylene and orlon are used as fibres. Fibres are the thread forming solids which possess high tensile strength and high modulus. These characteristics is due to strong intermolecular forces like hydrogen bonds.
