Options
- A. Ethane-1,2-diol and Benzene-1,3 dicarboxylic acid
- B. Propane-1, 2-diol and Benzene-1, 4 dicarboxylic acid
- C. Ethane-1,2-diol and Benzene-1, 4 dicarboxylic acid
- D. Ethane-1,2-diol and Benzene-1, 2 dicarboxylic acid
Answer
C. Ethane-1,2-diol and Benzene-1, 4 dicarboxylic acid
Step-by-step 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
