Answer A polymer is a material which is made of a large number of subunits. Each subunit is called monomer. Explanation Polythene is an example of polymer. It is polymer of ethene. A number of units of ethene join together and forms polythene. Thus, ethene is monomer and polythene is polymer. Polymers are of three categories: Natural polymers Synthetic polymers Semi-synthetic polymers Natural polymers are the polymers which are obtained in nature. Example: starch Synthetic polymers are the polymers which are man-made. Example: Teflon Semi-synthetic polymers are the polymers whose sources are natural and some modifications are done to improve the properties. Example: Vulcanised rubber Conclusion Thus, monomer combines in a large number to form polymers.

Polymers

Polymers are naturally occurring or synthetically produced large molecules or compounds which are made up of series of repeating units called monomers. They are joined together by chemical bonds. The term polymer is coined from Greek roots meaning 'many …

Question

Chapter 20, Problem 56A

Interpretation Introduction

Interpretation:

The term polymer and monomer is to be defined.

Concept introduction:

Poly means many and mer means unit. Thus, polymer is repetition of units.

Expert Solution & Answer

Answer to Problem 56A

A polymer is a material which is made of a large number of subunits. Each subunit is called monomer.

Explanation of Solution

Polythene is an example of polymer. It is polymer of ethene. A number of units of ethene join together and forms polythene. Thus, ethene is monomer and polythene is polymer.

Polymers are of three categories:

Natural polymers
Synthetic polymers
Semi-synthetic polymers

Natural polymers are the polymers which are obtained in nature. Example: starch

Synthetic polymers are the polymers which are man-made. Example: Teflon

Semi-synthetic polymers are the polymers whose sources are natural and some modifications are done to improve the properties. Example: Vulcanised rubber

Conclusion

Thus, monomer combines in a large number to form polymers.
