Question

State true or false.
Like synthetic fibres, plastic is also polymer.
A.True
B.False

Answer 1

Hint: Long repeating chains of molecules are joined together to form a polymer. A polymer is a substance or material consisting of huge molecules, or macromolecules which is a combination of the repeating units. There are natural polymers and synthetic polymers as well.

Complete step by step answer:
Synthetic fibers are made only from polymers found in natural gas and by-products of petroleum.
Synthetic fibers are man-made fibers. All fabrics are obtained from fibers, while fibers are obtained from artificial or man-made sources. They are made up of polymers which are made from repeating units of monomers.
Synthetic fibers are made by the polymerization of monomeric units.
Plastics is the term commonly used to describe a wide range of synthetic or semi-synthetic materials that are used in a huge and growing range of applications.
Plastics are polymers with very high molecular mass and contain different substances called monomers. They are usually synthetic, most commonly derived from petrochemicals, the variants are made from renewable materials such as polyacetic acid from corn or cellulose from cotton linters.
The raw materials used to produce plastics are natural products such as cellulose, coal, natural gas, salt, and crude oil.
Therefore we can say that both synthetic fibers and plastics are made by polymerization of its monomer units.
Thus the plastic is also polymer like synthetic fibers.
Thus the correct answer is (A).

Note:
Plastic is also a polymer like synthetic fiber. All plastics do not have the same type of arrangement of units. In some, it is linear whereas in others it is cross-linked. Plastics can be used in different ways. It can be colored, melted, rolled into sheets, or made into wires.
