Q49 / 150 · MHT CET 2026 (11 April Shift 1) · Chemistry
Which of the following compounds are used to obtain terylene polymer?
- AEthane-1,2-diol and Benzene-1,3 dicarboxylic acid
- BPropane-1, 2-diol and Benzene-1, 4 dicarboxylic acid
- Correct answerCEthane-1,2-diol and Benzene-1, 4 dicarboxylic acid
- DEthane-1,2-diol and Benzene-1, 2 dicarboxylic acid
Solution
Terylene, also known as Dacron, is a polyester.
It is prepared by the condensation polymerization of ethylene glycol and terephthalic acid.
The IUPAC name of ethylene glycol is ethane-1,2-diol.
The IUPAC name of terephthalic acid is benzene-1,4-dicarboxylic acid.
Therefore, the monomers used to obtain terylene are ethane-1,2-diol and benzene-1,4-dicarboxylic acid.
Answer: Ethane-1,2-diol and Benzene-1, 4 dicarboxylic acid
It is prepared by the condensation polymerization of ethylene glycol and terephthalic acid.
The IUPAC name of ethylene glycol is ethane-1,2-diol.
The IUPAC name of terephthalic acid is benzene-1,4-dicarboxylic acid.
Therefore, the monomers used to obtain terylene are ethane-1,2-diol and benzene-1,4-dicarboxylic acid.
Answer: Ethane-1,2-diol and Benzene-1, 4 dicarboxylic acid
Hence, the correct answer is option: 'C'.
