Which of the following is true about freons ?
  1. (A)These are chlorofluorocarbon compounds✓ Correct
  2. (B)These are chemicals causing skin cancer
  3. (C)These are radicals of chlorine and chlorine monoxide
  4. (D)All radicals are called freons

Answer: (A)

Solution

Freons are chlorofluorocarbons, organic molecules made of carbon, chlorine and fluorine that served as refrigerants and aerosol propellants. They are stable, closed-shell compounds rather than radicals; the chlorine atoms freed from them in the upper atmosphere destroy ozone, but the freons themselves are the chlorofluorocarbon compounds.
