Question

Match the Polymer with the most suitable Monomer combinations from which it is synthesized.

• A. P-4; Q-3; R-2; S-1
• B. P-4; Q-2; R-3; S-1
• C. P-2; Q-1; R-4; S-3
• D. P-2; Q-1; R-3; S-4

Hint:

Understanding the monomer combinations is crucial in identifying polymers. For example, polyurethanes come from diisocyanates and polyols, while polyimides often use bisphenol A and epichlorohydrin.

Answer 1

The Correct Option is A

This question requires us to match the correct polymer with the most suitable monomer combinations used in their synthesis. Let’s go through the options and match them appropriately:
- Polyurethane (P) is synthesized from the reaction of hexamethylene diisocyanate and tetramethylene glycol, making the correct monomer combination (4).
- Epoxy (Q) is synthesized from pyromellitic anhydride and p,p'-diaminodiphenyl ether, which is a typical method for producing epoxy resins, corresponding to (3).
- Polyimide (R) is synthesized from epichlorohydrin and bisphenol A, which forms the imide linkage required for polyimide synthesis, making it (2).
- Polyester (S) is commonly made from maleic acid and propylene glycol, which is a typical monomer combination used in the synthesis of polyester resins, corresponding to (1).
Thus, the correct matching is (A) P-4; Q-3; R-2; S-1.
