Question

Chloroprene is the monomer of:
1.PVC
2.Neoprene
3.Polystyrene
4.Polythene

Answer 1

This question gives the knowledge about the polymers. Simpler monomer units combine with each other to form polymers. Polymer is a Greek word which means “many parts”. Many polymers are present in our environment.

Complete step-by-step answer: Chloroprene is a monomer used for the formation of neoprene. The combination of various chloroprene units leads to the formation of neoprene.
The reaction to form neoprene from chloroprene is as follows:
$n\left[ {C{H_2} = C\left( {Cl} \right) - CH = C{H_2}} \right]\xrightarrow{{Polymerization}}{\left[ { - C{H_2} - C\left( {Cl} \right) = CH - C{H_2} - } \right]_n}$
Therefore, chloroprene is the monomer of neoprene.

Additional information: Polymers are the macromolecules which are formed by the combining of a number of simpler units known as monomers. Polymer is a Greek word which means “many parts”. Many polymers are present in our environment. Polymers can be naturally occurring or can be man-made. Polymers that are found in plants and animals naturally are known as natural polymers and the polymers that are man-made are known as synthetic polymers.
Uses of polymers are as follows:
Polypropene is a polymer which is used at a large scale in industries like aircraft, rope, toys, textiles and so forth.
Glyptal is very useful in making coatings, lacquers and paints.
Bakelite is a polymer which is useful in making toys, electrical switches, firearms, jewelry, insulators and kitchen products.
Polyvinyl chloride is useful for making sewage pipes, construction of windows and doors.

Hence, option $2$ is correct.

Note: Polymer is a Greek word which means “many parts”. Polymers are the macromolecules which are manufactured by the combination of various smaller units known as monomers. Polymers can be naturally occurring or can be synthesized in laboratories.
