Polymerization of which monomer produces neoprene?

1. CCl2=CCl2
2. CH2=C(Cl)–CH=CH2
3. CF2=CF2
4. CH2=CHCl

Correct answer: CH2=C(Cl)–CH=CH2

Solution

The correct option, CH2=C(Cl)–CH=CH2, contains a vinyl group that can undergo polymerization to form neoprene, a synthetic rubber. This process involves the addition of the monomer's double bonds to create long polymer chains.
