Question:
Which of the following polymers has ester linkage?
Which of the following polymers has ester linkage?
Show Hint
Polyester means ester linkage. Which one is it?
Updated On: Oct 1, 2026
- Orlon
- Dacron
- Teflon
- Neoprene
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
An ester linkage is \(-COO-\). Polyesters are made by condensing a diacid with a diol.
Step 2: Check each polymer:
Orlon (polyacrylonitrile) is an addition polymer with nitrile groups. Dacron (terylene) is made from terephthalic acid and ethylene glycol, so it has ester links. Teflon is polytetrafluoroethylene with only C-F and C-C bonds. Neoprene is polychloroprene, a hydrocarbon rubber with Cl.
Step 3: Conclusion:
Only Dacron has ester linkages, option (B).
Final Answer:
Dacron is a polyester. \[ \boxed{B:\ \text{Dacron}} \]
