Q17.
Consider the following statements: Chlorofluorocarbons, known as ozone-depleting substances, are used 1. In the production of plastic foams. 2. In the production of tubeless tyres. 3. In cleaning certain electronic components. 4. As pressurizing agents in aerosol cans. Which of the statements given above is/are correct?
Answer
C
Explanation
CFCs are used in: production of plastic foams (as blowing agents), cleaning certain electronic components (as solvents), and as pressurizing agents in aerosol cans. CFCs are NOT used in the production of tubeless tyres — statement 2 is incorrect. MRF developed eco-friendly car radials that moved away from CFC use, highlighting that tyres don't typically use CFCs in their production.
