Which of the following compounds is responsible for depletion of ozone layer?
- A Freon
- B Chloroform
- C DDT
- D Iodoform
Answer & Solution
Correct Answer
(A) Freon
Step-by-step Solution
Detailed explanation
Freons are chlorofluorocarbons introduced into the atmosphere from aerosol sprays and refrigerating equipments. They have a very long life time and when they reach stratosphere, they undergo photochemical decomposition and destroy ozone by the following sequence of reactions.…
