Question
Which of the following organic compounds polymerises to form the polyester dacron?
A.
Propylene and $$para$$ $$ - HO - \left( {{C_6}{H_4}} \right) - OH$$
B.
Benzoic acid and ethanol
C.
Terephthalic acid and ethylene glycol
D.
Benzoic acid and para $$ - HO - \left( {{C_6}{H_4}} \right) - OH$$
Answer :
Terephthalic acid and ethylene glycol
Solution :
Dacron, commonly known as terylene, is obtained by heating a mixture of terephthalic acid and ethylene glycol at $$420-460$$ $$K$$ in the presence of zinc acetate and antimony trioxide as a catalyst.
