Question

Among the following a natural polymer is
A. Cellulose
B. PVC
C. Teflon
D. Polyethylene

Answer 1

Hint: A polymer which occurs naturally from any plant and animal is called a natural polymer. Cellulose is a natural plant material. It is a polymer of glucose.

Complete step by step solution:
Polymers are formed by the addition of two or more monomers. The polymers can be classified into various categories but according to the sources it can be classified into two main classes. One is natural polymer and the other one is brunch polymer.

Natural polymers are obtained from natural elements or natural sources. Some examples of natural polymers are cellulose, nucleic acid, protein etc.

The polymer which is prepared in the laboratory by chemical treatment is called synthetic polymer. It is actually man made polymers. Some examples of synthetic polymers are PVC, polyethylene, Teflon etc.
PVC is a linear polymer of vinyl chloride. It is prepared by a chain reaction.

Polyethylene is a linear polymer of ethylene or ethene. It is prepared by a chain reaction. Teflon is a linear polymer of tetrafluoroethylene. It is also called polytetrafluoroethylene. It is prepared by a chain reaction. Thus the natural polymer is cellulose.
Thus the correct option is A.

Note: The monomer of cellulose is alpha-D glucose. It has 1-4 linkage of alpha-D glucose. By the action of acetate upon cellulose a semi synthetic polymer named as cellubiouse is obtained.
