Question

Substitute of chlorofluorocarbon is

• A. Hydrofluorocarbon
• B. Hydrochlorofluorocarbon
• C. Fluorocarbon
• D. Both A and B

Answer 1

Answer: (D)

Both A and B

Chlorofluorocarbons (CFC) are the chemicals used as refrigerants. They cause ozone depletion as they release chloride radicals which on reacting with ozone causes its degradation.

The chlorofluorocarbons can be substituted by Hydrofluorocarbon (HFC) or Hydrochlorofluorocarbon (HCFC) for using as refrigerants and in air conditioners. Though HFCs and HCFCs also deplete ozone but to lesser extent than CFCs.

Hence, both options A and B are correct.

So, the correct answer is 'Both A and B'.
