Question

Which of the following is not an example of natural polymer?
A.Wool
B.Silk
C.Leather
D.Nylon

Answer 1

Hint:To answer this question, you should recall the concept of polymerization. Polymerization refers to the process of molecules called monomers reacting together and produces three-dimensional networks or polymer chains are called polymerization.

Complete answer:
A polymer is a large molecule or a macromolecule which essentially is a combination of many subunits. Polymers are all created by the process of polymerization wherein their constituent elements called monomers, are reacted together to form polymer chains. Polymers may be naturally found in plants and animals (natural polymers) or may be man-made (synthetic polymers). Different polymers have a number of unique physical and chemical properties due to which they find usage in everyday life.
Wool is obtained from animals, silk is obtained from insects. Leather is obtained from animal skins. From the given options Nylon is not a natural polymer.

Hence, the correct option is option D.

Note:
You should know about the different types of polymers. We can, therefore, classify polymers based on the Source of Availability. There are three types of classification under this category, namely, Natural, Synthetic, and Semi-synthetic Polymers.
Natural Polymers: They occur naturally and are found in plants and animals. For example, proteins, starch, cellulose, and rubber. To add up, we also have biodegradable polymers which are called biopolymers.
Semi-synthetic Polymers: They are derived from naturally occurring polymers and undergo further chemical modification. For example, cellulose nitrate, cellulose acetate.
Synthetic Polymers: These are man-made polymers. Plastic is the most common and widely used synthetic polymer. It is used in industries and various dairy products. For example, nylon-6, 6, polyether etc.
