Question

Which of the following represents the correct match for items in Column A with those in Column B.
$$\begin{array}{cc}\text{Column A}& \text{Column B}\\ \text{I. Nylon}& \text{(i) Thermoplastic}\\ \text{II. PVC}& \text{(ii) Thermosetting plastic}\\ \text{III. Bakelite}& \text{(ii) Fiber}\end{array}$$

• A. I-(ii), II-(iii), III-(i)
• B. I-(iii), II-(i), III-(ii)
• C. I-(ii), II-(i), III-(iii)
• D. I-(iii), II-(ii), III-(i)

Answer 1

The correct option is B

I-(iii), II-(i), III-(ii)

Polymers are classified into fibres and plastics on the basis on forces between the polymer chains.

Nylon:- Synthetic fibre (The fibres that are produced by humans with chemical synthesis)

Polyvinyl Chloride:- Thermoplastic (Plastics which can be moulded in desired shapes when heated)

Bakelite:- Thermosetting plastic (Plastics which when once moulded cannot be softened by heating)
