Answer:
Correct Answer: 1. (a)
Solution:
- Bakelite is a thermosetting polymer. These polymers are cross-linked or heavily branched molecules which on heating undergo extensive cross linking in moulds and become infusible. Once they get set, they cannot be reshaped and reused.
(C) $\mathrm{OH}$
(D)
Thus, the correct match is as follows :
(A) $\rightarrow$ (III), (B) $\rightarrow$ (I), (C) $\rightarrow$ (IV), (D) $\rightarrow$ (II)
