Question

Terylene is a-

• A. Polyether
• B. Polymide
• C. Polyester
• D. Long-chain hydrocarbon

Answer 1

The correct option is C

Polyester

Explanation for correct answer:-

Option (C) Polyester

• Polyesters are polymers that have ester linkages resulting from the condensation of the carboxylic group and hydroxyl group in monomeric units.
• Terylene is formed due to the ester linkage formation between Ethane-1,2-diol and terephthalic acid monomer unit.

Explanation for Incorrect answers:-

Option (A) Polyethers:

• They are polymers that have ether linkage resulting from the condensation of monomeric units. However, the monomers of terylene form ester linkage.

Option (B) Polyamides:

• They are polymers that have amide linkage resulting from the condensation of monomeric units. However, the monomers of terylene form ester linkage.

Option (D) Long chain hydrocarbon:

• These are polymers having carbon and hydrogen atoms. Terylene contains oxygen atoms as well. Hence it is not a long chain hydrocarbon.
