Question

Like synthetic fibres, plastic is also a:
(A) polymer
(B) polythene
(C) polycot
(D) acrylic

Answer 1

Hint: Synthetic fibres are those chemical compounds that are generally made up of the repeating structural units of the long chains and are synthetic and manmade and plastic similarly is also synthetic, man-made and formed of the repeating units by the process of polymerization.

Complete step by step solution:
-By the synthetic fibres, we mean those fibres which are created from the natural materials like wood pulp etc. or those which are prepared from the chemical processes and are thus, man-made. E.g. rayon, nylon, polyester etc. They are stronger and more durable and thus are preferred over the natural fibres. They are polymers (they are long repeating chains of the molecules that are bonded together) and are made from the small molecules of polymers.
-On the other hand, plastics like synthetic fibres are synthetic organic substances and are polymers like synthetic fibres. They are the organic materials like the wood, paper etc. and the raw materials required to produce plastics are cellulose, crude oil, salt etc. They are very soft and can be moulded into any shape and after that, they are hardened. They are not damaged by water, heat, chemicals etc. and are widely used in construction, decoration purposes, for making articles, for coating etc.
-So, from the above, it is clear that the plastics are organic polymers.

Hence, option (A) is correct.

Note: The plastics may not have the same types of the arrangement of monomers in them and in some, they have linear arrangements of monomers and in the others, they have cross-linked arrangements of monomers.
