Consider the following statements:Chlorofluorocarbons, known as ozone-...
Explanation:
Chlorofluorocarbons (CFCs) are a group of chemicals that contain chlorine, fluorine, and carbon. They were commonly used as refrigerants, solvents, and propellants in aerosol cans. However, CFCs are known to be ozone-depleting substances, which means that they break down the ozone layer in the Earth's atmosphere, leading to increased levels of ultraviolet radiation reaching the Earth's surface.
The statements given in the question are:
1. In the production of plastic foams
CFCs were commonly used as blowing agents in the production of plastic foams, including foam insulation and foam packaging materials.
2. In the production of tubeless tyres
There is no known use of CFCs in the production of tubeless tyres.
3. In cleaning certain electronic components
CFCs were commonly used as solvents in the cleaning of electronic components, such as circuit boards and computer chips.
4. As pressurizing agents in aerosol cans
CFCs were commonly used as propellants in aerosol cans, which are used for a wide range of products, including spray paints, deodorants, and hair sprays.
Therefore, the correct statements are 1, 3, and 4. Statement 2 is incorrect. The correct answer is option C.
