Question

Which among the following is a synthetic polymer? (a) Rubber (b) Teflon (c) DNA (d) Wool

Answer 1

Hint: Polymers are macromolecules consisting of many repeating units. Natural and synthetic polymers are the two types of polymers. Synthetic polymers are made by man.

Complete answer:
Synthetic polymers are those polymers which are made by man. Amongst the given examples, Teflon is the synthetic polymer while the other i.e. rubber, wool and DNA are natural polymers. Rubber and wool are derived from plants while DNA is present in animals. The polymerization reaction for the synthesis of Teflon is given as:

In the above reaction, tetrafluoroethylene acts as a monomer and leads to the formation of polytetrafluoroethylene (PTFE) as a polymer product. Polytetrafluoroethylene is called teflon. It is an example of an additional polymer which is formed via chain growth (free-radical) polymerization.
In all, we can say that among the following polymers, teflon is a synthetic polymer.
So, the correct answer is “Option b”.

Additional information: Teflon has numerous applications. For instance: Teflon is used as a non-sticky coating material on the utensils which is used for cooking purposes. Besides, Teflon is also used for coating the wires. Moreover, Teflon is a thermoplastic polymer which becomes mold on heating and solidifies upon cooling.

Note:
 It is important to note that Teflon is the synthetic polymer while the other three i.e. rubber, wool and DNA are natural polymers. Teflon is called polytetrafluoroethylene in which the monomeric unit is tetrafluoroethylene. Teflon is an example of an additional polymer which is formed via chain growth (free-radical) polymerization.
