Question

which one of the following structures represents the neoprene polymer?
(a)

(b)

(c)

(d)

Answer 1

Hint: Neoprene comes under the category of synthetic rubber and is formed by the polymerization of the free radical of 2-chlorobutan-1,3-diene. Now you can easily answer the given statement accordingly.

Complete step by step answer:
First of all, we should know what polymers actually are. Polymers are the high molecular mass compounds, obtained by joining together a larger number of simple molecules through covalent bonds in a regular manner. And the simple molecules which combine to form a polymer are called the monomers and this process of formation of the polymers is known as polymerization.
- Now consider the statement as:
Neoprene is a synthetic rubber i.e. a polymer that is capable of getting stretched to about twice its length and it returns to its original shape and size as soon as the external stretching force is released. These have properties similar to rubber and some additional desirable properties.
It is prepared by the free radical polymerization of chloroprene (2-chlorobuta-1,3-diene) as:

So, the correct answer is “Option D”.

Note: Neoprene is superior to natural rubber in its stability to aerial oxidation and its resistance to vegetable and mineral oils, gasoline, and other solvents. It is used as an insulator, making conveyor belts, hoses, etc.
