Which of the following organic compounds polymerizes to form the polyester Dacron?Which of the following organic compounds polymerizes to form the polyester Dacron?

Options

  1. APropylene and para HO−(C6H4)−OHHO - \left({C}_{6}{H}_{4}\right) - OH
  2. BBenzolic acid and ethanol
  3. CTerepthalic acid and ethylene glycol
  4. DBenzoic acid and para HO−(C6H4)−OHHO - \left({C}_{6}{H}_{4}\right) - OH

Correct answer

C. Terepthalic acid and ethylene glycol

Step-by-step solution

Terepthalic acid and ethylene glycol polymerizes to form the polyester Dacron as shown in the figure.

Dacron, commonly known as terylene, is obtained by heating a mixture of terephthalic acid and ethylene glycol at 420−460K420 - 460K in the presence of zinc acetate and antimony trioxide as a catalyst.
