Answer 2

You have asked about the neoprene structure, the correct answer is Option (a).

Explanation:

First thing that you need to keep in mind is that neoprene is only a brand name that is given by DuPont Elastomers.

It is known by the name Chloroprene rubber and is widely available commercially as 2-cholo-1, 3-butadiene or trans-1,4-Polychloroprene.

There is a chlorine attached to the chain which basically reduces the reactivity and makes the rubber more resistant to harsh chemicals.

This form of rubber is resistant to oils, chemicals, water, other liquids, solvent, certain acids and also to fuels.

Another important property of neoprene rubber is that it is also considered as best resistant to flames. It is self extinguishing type of rubber material that is widely used commercially.

Structural formula:-

[-CH2 –C= CH-CH2-]n.

So, here the correct answer is option (a).
