Question

The following are synthetic polymers except:
A.Teflon
B.Terylene
C.Nylon
D.Protein

Answer 1

Hint: Synthetic polymers are the man made polymers which are being created in the labs and industries, in order to make clothes and other useful materials.
For a monomer to be appropriate, it should have two reaction sites.

Complete step by step answer:
Polymers are repeating units of the same kind of molecules called monomers.
There exist two types of polymers namely, synthetic and natural polymers. Synthetic polymers can be defined as those polymers which are derived from petroleum oil, and prepared by engineers and scientists. Some examples of synthetic polymers may include, polyester, polyethylene, nylon, epoxy and Teflon.

On the other hand Natural polymers are those which occur in nature and can be extracted by following different extraction methods. Some of the well-known Examples of naturally occurring polymers may include proteins, wool, silk, and cellulose.
Now if we consider the options given in the question, we are supposed to find out which is not synthetic polymer as in which is a natural polymer among all of those.
If we consider the first option i.e., option A, Teflon is a synthetic polymer and is prepared by the industries in huge amounts, as it has a very significant industrial application. Therefore, this option is incorrect.
Terylene is the second option, it is also a synthetic polymer and has a wide range of applications.
Its main application is in making clothing and plastic bottles. So this is not the correct option.
The next option is nylon, which is also a synthetic polymer. You may have heard about the ropes made of nylon, and the clothes, fibres. It has a huge range application and it has high tensile strength. So this option is incorrect.
This leaves us with the last option, which is protein. Now we all know protein is one of the main components of living organisms. It helps in growth of muscle cells.
given below are the types in which protein could exist, naturally.

Since it is a naturally existing polymer, the correct answer is option D.

Note:
There are various sources from which we could get protein such as other animals, pulses, soybean seeds etc.
Some more applications of terylene include: Terylene fiber is used as polyester tricot knit as a fashion garments fabric. Also for the usage of laundry purposes as an automatic clothing vacuum packaging machine.
