Question

Match the entries of column I with column II
$$\begin{array}{cc}\text{Column A}& \text{Column B}\\ \text{(a) First artificial plastic}& \text{(i) Polythene}\\ \text{(b) First artificial fibre}& \text{(ii) DNA}\\ \text{(c) Biopolymer}& \text{(iii) Nylon}\\ \text{(d) Linear polymer}& \text{(iv) Bakelite}\end{array}$$

• A. (a) - (iv), (b) -(ii), (c) - (iii), (d) - (i)
• B. (a) - (iv), (b) -(iii), (c) - (ii), (d) - (i)
• C. (a) - (iii), (b) -(iv), (c) - (i), (d) - (ii)
• D. (a) - (i), (b) -(ii), (c) - (iii), (d) - (iv)

Answer 1

The correct option is B

(a) - (iv), (b) -(iii), (c) - (ii), (d) - (i)

Bakelite:- It is the first artificially prepared plastic by Belgian chemist Leo Baekeland in 1909.

Nylon:- It is the first artificially prepared fibre which got its name from the names of the cities, New York and London.

DNA (Deoxyribonucleic acid):- It belongs to the category of biopolymers because it is found in living beings.

Linear Polymer:- Polythene is a linear chain polymer because monomer units (ethene) combine in a linear form to form this polymer.
