The correct answer is A. Chloroprene.
Neoprene is a synthetic rubber that is made from chloroprene, a monomer that is derived from petroleum. It is a versatile material that can be used in a variety of applications, including tires, hoses, and gaskets. Neoprene is resistant to water, oil, and chemicals, and it is also flame-retardant.
Isoprene is a hydrocarbon that is found in natural rubber. It is a monomer that can be used to make a variety of polymers, including synthetic rubbers and plastics. Isobutane is a hydrocarbon that is used as a fuel and refrigerant. Isopentane is a hydrocarbon that is used as a solvent and fuel.
Chloroprene is a monomer that is used to make neoprene. It is a colorless, flammable liquid that is derived from petroleum. Chloroprene is a hazardous material that can cause skin and eye irritation, and it can also be harmful if inhaled or ingested.
