The correct answer is A. 1 and 2.
Acetone is a colorless, flammable liquid that is used as a solvent in many industrial and commercial applications. It is also used to make chloroform, artificial leather, and other chemicals. Benzene Hexachloride (BHC) is a powerful insecticide that is used to control a variety of pests, including mosquitoes, flies, and ticks. Carbon tetrachloride is a colorless, non-flammable liquid that is used as a solvent and refrigerant. It is also used in fire extinguishers under the name pyrene.
However, carbon tetrachloride is no longer recommended for use in fire extinguishers because it is a suspected carcinogen. It is also a greenhouse gas and can contribute to ozone depletion.
Here is a brief explanation of each option:
- Option 1: Acetone is used for making chloroform, artificial leather.
Acetone is a colorless, flammable liquid that is used as a solvent in many industrial and commercial applications. It is also used to make chloroform, artificial leather, and other chemicals.
Chloroform is a colorless, flammable liquid that is used as an anesthetic and a solvent. It is also used to make other chemicals, such as carbon tetrachloride.
Artificial leather is a material that is made to look like leather. It is made from a variety of materials, including polyurethane, PVC, and nylon.
- Option 2: Benzene Hexachloride (BHC) is powerful insectiside.
Benzene Hexachloride (BHC) is a powerful insecticide that is used to control a variety of pests, including mosquitoes, flies, and ticks. It is also used to control agricultural pests, such as insects that damage crops.
- Option 3: Carbon tetrachloride used as a fire extinguisher under the name pyrene.
Carbon tetrachloride is a colorless, non-flammable liquid that is used as a solvent and refrigerant. It is also used in fire extinguishers under the name pyrene.
Pyrene is a type of fire extinguisher that uses carbon tetrachloride as the extinguishing agent. It is effective against Class B and C fires, which are fires that involve flammable liquids and gases, and electrical fires.
However, carbon tetrachloride is no longer recommended for use in fire extinguishers because it is a suspected carcinogen. It is also a greenhouse gas and can contribute to ozone depletion.
