Updated On: Oct 1, 2026
- Ethane-1,2-diol and Benzene-1,3 dicarboxylic acid
- Propane-1, 2-diol and Benzene-1, 4 dicarboxylic acid
- Ethane-1,2-diol and Benzene-1, 4 dicarboxylic acid
- Ethane-1,2-diol and Benzene-1, 2 dicarboxylic acid
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Recall the monomers
Terylene (Dacron, PET) is a polyester from ethane-1,2-diol and benzene-1,4-dicarboxylic acid (terephthalic acid).
Step 2: Check
Isophthalic acid (1,3) and phthalic acid (1,2) give other polymers, and propane-1,2-diol is not used. Option (C).
Final Answer:
Ethane-1,2-diol and benzene-1,4-dicarboxylic acid, option (C). \[ \boxed{\text{(C)}} \]
