Answer 1

Hint: Polymer is a term used to describe a substance or a material made up of very large molecules or macromolecules made up of several repeating subunits. Both natural and manmade polymers play important roles in our daily lives because of their wide range of applications.

Complete Step by Step Solution:
The monomer is a compound which is the fundamental unit of polymers. Caprolactam is a monomer of nylon-6. Nylon-6 is produced by using caprolactam as follows:
Therefore, the right pair is (i)→(c).

An example of synthetic rubber is Buna-N. 1,3-Butadiene and acrylonitrile are copolymerized to create it. The catalyst is peroxide. One of the monomers in BUNA-N is acrylonitrile.
Therefore, the right pair is (ii) →(b).
Previously, acetylene was converted to mono vinyl acetylene by treating it with cupric chloride, which was then converted to chloroprene by treating it with hydrochloric acid. Chloroprene free-radical polymerization produces neoprene.

During industrial processing, this polymer is created via free-radical emulsion polymerization. Polymerization is started using potassium persulfate. Bifunctional nucleophiles, metal oxides (such as zinc oxide), and thioureas are utilised to crosslink distinct polymer chains. To transform chloroprene into rubber, it is emulsified in water and then polymerized by the action of free-radical initiators. In the resultant polymer chain, the chloroprene repeating unit can adopt several configurations; trans-polychloroprene being the most prevalent. Neoprene is a monomer of 2-chlorobuta-1,3-diene, sometimes referred to as chloroprene.
Therefore, the right pair is (iii) →(a).

The organic component isoprene found in the bark of tropical and subtropical trees is naturally polymerized to form natural rubber. Latex is the milky-white liquid that comes from trees. Because of this, natural rubber is often referred to as latex. Natural rubber is also known as caucho, India rubber, and Amazonian rubber. Thailand and Indonesia are the top two producers of natural rubber. Natural rubber is produced by polymerizing 2-methylbuta-1,3-diene.
Therefore, the right pair is (iv) →(d).

As a result, the correct answer is option C.

Note: Because caprolactam is an irritant and a somewhat poisonous substance, we should exercise caution when handling it. It was listed as one of the dangerous air pollutants. We should be aware that when caprolactam is added to water, it hydrolyzes to aminocaproic acid, a drug.
