Question

Match the following:

• A. A - III, B - I, C - IV, D - II
• B. A - III, B - IV, C - I, D - II
• C. A - I, B - II, C - III, D - IV
• D. A - IV, B - III, C - II, D - I

Hint:

When identifying polymers:
- Elastomers are stretchable, like rubber.
- Fibres are used in textiles and have strong intermolecular forces.
- Thermoplastics soften upon heating and can be reshaped.
- Thermosetting polymers undergo irreversible hardening.

Answer 1

The Correct Option is A

- Buna-N rubber is categorized as an Elastomer, making \( A \) match with III.
- Terylene is a Fibre polymer, which aligns \( B \) with I.
- Polystyrene falls under Thermoplastic polymers, so \( C \) corresponds to IV.
- Urea-Formaldehyde resin is a Thermosetting polymer, thus \( D \) aligns with II.
Therefore, the correct answer is Option (1): \( A - III, B - I, C - IV, D - II \).
