Q. The Hydrochlorofluorocarbons (HCFCs) are the compounds which have the following molecules:
- Hydrogen
- Carbon
- Chlorine
- Fluorine
Which among the above plays the most important role in Ozone depletion?
Answer:
Chlorine
Notes: Ozone molecules got destroyed when the chlorine and bromine atoms come into contact with ozone in the atmospheric layer of stratosphere. CFC (Chlorofluoro carbon) slowly moves upward to the stratosphere and are broken up by ultraviolet radiation, which releases chlorine atoms.
