Question

Which of the following is a natural polymer?
A) Bakelite
B) Polythene
C) Buna-S
D) Protein

Answer 1

We know that a polymer may be a substance or material consisting of very large molecules or macromolecules composed of the many repeating subunits. There are 2 varieties of polymers: artificial and natural. Artificial polymers are derived from fossil fuel oil, and created by scientists and engineers while natural polymers occur in nature.

Complete step by step answer:
We know that the synthetic polymers embrace nylon, polyethylene, polyester, Teflon, and epoxy. Natural polymers are produced from nature and might be extracted. They’re usually water-based. Samples of present polymers are silk, natural rubber, wool, DNA, polysaccharide and proteins.
We must remember that the Bakelite or polyoxybenzylmethylenglycolanhydride was the primary plastic made up of artificial components. Therefore, option A is wrong.
Polythene is the commonest synthetic plastic in use today. Therefore, option B is wrong.
As we know that the Buna-s is a synthetic rubber. Therefore, the option C is wrong.
In case of Protein which is a natural polymer obtained from animals and plants.
Therefore, the option D is correct.

Note:
We must remember that the fibers are classified as natural and artificial to support their source and this classification results in easy understanding but it's very hard to classify them. The name natural fibers imply that they're directly got from nature. They experience a synchronized process of cleansing to suit our needs although it ruins natural fibers as their main constituent is directly obtained from nature. Some of the examples of natural fibers are Cotton, jute, silk, wool. Synthetic fibers are completely man-made. All the major ingredients that form the motivation of those fibers are produced unnaturally. Orlon is an example of artificial fibers. Orlon can be a class of acrylic that's greatly immune to temperatures and chemicals.
