Neoprene is prepared by polymerisation of which of the following A. 2-chloro-1, 3-butadiene B. 2-methyl 1, 3-butadiene C. 1,3-butadiene D. Acrylonitrile

2-chloro-1, 3-butadiene
2-methyl 1, 3-butadiene
1,3-butadiene
Acrylonitrile

The correct answer is: C. 1,3-butadiene.

Neoprene is a synthetic rubber that is prepared by the polymerization of 1,3-butadiene. It is a versatile material that is used in a variety of applications, including tires, hoses, and gaskets. Neoprene is resistant to oil, grease, and sunlight, and it has good electrical insulation properties.

2-chloro-1,3-butadiene is a monomer that is used to produce neoprene. It is a colorless liquid that is flammable and toxic. 2-chloro-1,3-butadiene is a hazardous material that must be handled with care.

2-methyl-1,3-butadiene is a monomer that is used to produce butyl rubber. It is a colorless liquid that is flammable and toxic. 2-methyl-1,3-butadiene is a hazardous material that must be handled with care.

Acrylonitrile is a monomer that is used to produce acrylic fibers and plastics. It is a colorless liquid that is flammable and toxic. Acrylonitrile is a hazardous material that must be handled with care.
