Question

The monomer used to prepare polyvinyl polythene is
(A) Vinyl chloride and ethane
(B) ethene
(C) 1, 3 – butadiene and acrylonitrile
(D) 1, 3 – butadiene

Answer 1

Hint:To solve this question firstly we shall understand about the monomer. What is monomer? Monomer is a molecule of any of s class of compound mostly organic that can react with another molecule to form a very large molecule or polymer. We will study all the related information and hence this will help us in approaching our answer.

Complete step-by-step answer:
> Polyvinyl polythene is a thermoplastic Material made from ethylene with property depending on the molecular weight.
> Polyvinyl polythene is obtained by the 1,2 polymerizations of 1,3 – butadiene.
> Polymerization is a process of reacting monomer molecules together in a chemical reaction to form a polymer chain or 3-dimensional network. There are many forms of polymerization and different systems exist to categorize them. Chemical compound polymerization can occur via a variety of reaction mechanisms that vary in complexity due to functional groups present on it. In the reactant and their inherent steric effect. In the case of alkene form polymers through relatively simple radical reactions. In contrast, reactions involving substitution at a carbonyl group require more complex synthesis due to the way in which reactant polymerizes. Alkanes can also be polymerized but only with the help of strong acid.
> Hence, as we can see 1,3- Butadiene is the monomer used to prepare polyvinyl polythene.
Hence, the correct answer is option (D) .

Note: Polymer is the most common form of plastic used in the packaging industries, to make the container, bottle toys, plates etc are some polymers used in daily life. Organic polymers often play a very important role in living organisms, provide basic structural materials to them and also participate in various vital life processes. For example, Starch in plants, silk, proteins, hair, etc. Polyester and polyethylene are some examples of man-made(synthetic) polymers.
