- $C_{6}H_{5}$ and $CH_{2}O$
- $H_{2}C=CH-CH=CH_{2}$ and $H_{2}C=CH-CN$
- $HO(CH_{2})_{2}-OH$ and $HO-C(=O)-C_{6}H_{4}-C(=O)-OH$
- $H_{2}C=CH-CN$ and $C_{6}H_{5}OH$
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
Dacron (Terylene) is a polyester.
Step 2: Meaning
It is formed by the condensation polymerization of a diol and a dicarboxylic acid.
Step 3: Analysis
- Monomer 1: Ethylene glycol ($HO-CH_{2}-CH_{2}-OH$). - Monomer 2: Terephthalic acid ($p-HOOC-C_{6}H_{4}-COOH$).
Step 4: Conclusion
Option (C) correctly represents these two monomers. Final Answer: (C)
