Question

Terylene is a condensation polymer of ethylene glycol and

• A. benzoic acid
• B. phthalic acid
• C. salicylic acid
• D. terephthalic acid

Hint:

Terylene (PET) is commonly used in the production of synthetic fibers and plastic bottles, and is formed by the polymerization of terephthalic acid and ethylene glycol.

Answer 1

The Correct Option is D

Terylene, also known as PET (polyethylene terephthalate), is a condensation polymer formed by the reaction of ethylene glycol with terephthalic acid.
This process forms long chains, and terephthalic acid is the correct monomer in this case.

Thus, the correct answer is (d).
