Question

Identify synthetic polymer amongst the following:
(A) Linen
(B) Jute
(C) Silk
(D) Terylene

Answer 1

Hint: Polymers are macromolecules built up by linking together a large number of small molecules. The repeating units in a polymer are linked with strong covalent bonds. Small molecules that combine to form polymer molecules are called monomers. The process of synthesis of the polymer is known as the polymerization process, which is used to prepare synthetic polymers.

Complete step by step solution:
The polymers are mainly classified into many types based on their physical and chemical properties. They are,
Based on source
Based on monomers
Based on polymerization
Based on functionality
Based on intermolecular forces
Based on structure
Based on source: polymers are classified into two types based on the availability of a source of abundance in nature. Those are natural polymers and synthetic polymers
(1) Natural polymers: these are obtained either from plants or animals. For example, cellulose, jute, linen, silk, etc.

(2) synthetic polymers: this variety of polymers as plastic, synthetic fibers, and synthetic rubbers are examples of man-made polymers prepared in daily life as well as in industry or laboratories. These synthetic polymers are made by the polymerization process.
For example, PVC, Teflon, Terylene, etc.
Hence, except for Terylene is a synthetic polymer and remaining given polymers jute, linen, silk are natural polymers.

So, the correct answer is option D.

Note: Terylene is a type of synthetic rubber and is also known as Dacron. This is a form of polymer that is formed with ester groups attached to the main chain and it is synthesized by condensation polymerization of Terephthalic acid and ethylene glycol. This is high tensile strength and good resistance to chemical degradation by chemical bleaches.
