AIIMS 2019 Chemistry Types of Polymers Multiple Correct Question
Match following coloumn:
| Polymer :--- | Monomer :--- |
|---|---|
| (i) Buna-S | (P) Styrene |
| (ii) ethylene glycol | (Q) terylene |
| (iii) elastomer | (R) chloroprene |
(i) - (P) (ii) - (Q) (iii) - (R)
(i) - (R) (ii) - (P) (iii) - (Q)
(i) - (Q) (ii) - (R) (iii) - (P)
(i) - (P) (ii) - (R) (iii) - (Q)
Correct Answer
Detailed Explanation
Option A is correct because Buna-S is indeed a copolymer made from the monomers 1,3-butadiene and styrene, which are used to create synthetic rubber. However, Terylene is actually a polyester formed from ethylene glycol and terephthalic acid, not just "terephthalic acid," making option B incorrect. Option C is misleading as it states that chloroprene is the sole monomer for elastomers; while chloroprene is used to make neoprene, not all elastomers are derived solely from it. Thus, only the description of Buna-S in option A is fully accurate.
