Consider the following statements: Chlorofluorocarbons, known as ozone-depleting substances, are used

in the production of plastic foams
in the production of tubeless tyres
in cleaning certain electronic components
as pressurizing agents in aerosol cans

Which of the statements given above is/are correct?

Select an option to attempt

Explanation

Chlorofluorocarbons (CFCs) are synthetic compounds that contain chlorine, fluorine, and carbon. They have been a significant environmental concern due to their role in ozone depletion.

Chlorofluorocarbons (CFCs) were commonly used in the production of plastic foams, such as those used in insulation and packaging materials.

CFCs are not typically used in the production of tubeless tires. Instead, they are often used in the vulcanization process of rubber, which gives tires their durability.

CFCs were used in cleaning certain electronic components due to their solvent properties. However, their use in this application has been significantly reduced due to environmental concerns.

CFCs were commonly used as pressurizing agents in aerosol cans, such as those used for hairspray, deodorant, and household cleaning products.

So, statements 1, 3 and 4 are correct.
