Terephthalic acid and ethylene glycol organic compounds polymerizes to form the polyester Dacron.
Correct answer - "c".
Step by step explanation:
- Dacron is a synthetic polyester with strong, elastic properties used as synthetic cloth.
- And it is important fabric content in chemical fabrics but it is not a fabric itself.
- Dacron is the former term and its scientific name is polyester.
- And the chemical name of this compound is is polyethylene glycol terephthalate.
- The condensation polymerization of ethylene glycol and terephthalic acid forms dacron.
