Question

As plastics and synthetic fibres consist of repeating monomer units, they are known as __________.

Answer 1

Hint: A monomer is a substance that acts as the building block for polymers, which are made up of proteins. Polymerization is the mechanism by which monomers bind to other monomers to form repeated chain molecules.

Complete step-by-step answer:
Let us first understand what plastic and synthetic fibres are.
Plastics, including wood, paper, and fur, are organic materials. Natural products such as cellulose, natural gas, coal, salt, and, of course, crude oil are used as the primary products in the production of plastics. Polymers make up the majority of plastic materials.

Synthetic fibres are man-made fibres, the majority of which are made from petroleum-based raw materials such as petrochemicals. Fibres are used to make all fabrics, and they may come from natural or artificial sources. Polymers are made up of a small unit or polymer that is made up of several repeated monomers.

Now, let us understand what a polymer is.
A polymer is a material or substance made up of several repeated subunits that make up very large molecules or macromolecules. Both natural and synthetic polymers play important and pervasive roles in daily life due to their wide range of properties.

Therefore, we can conclude that plastics and synthetic fibres consist of repeating monomer units. They are known as Polymers.

Note: Polymers are used in almost every aspect of our daily life. Polymers can be used in grocery bags, soda and water bottles, cloth fabrics, tablets, laptops, food packaging, auto parts, and toys. Polymers are also used in more advanced manufacturing.
