Question

Write a short note on excessive use of man-made compounds containing both fluorine and chlorine.

Answer 1

Effects of excessive use of man-made compounds containing both fluorine and chlorine:

1. CFC (chloro-fluoro-carbon) gas, which contains fluorine and chlorine and is relatively stable, is known to be utilized in freezers.
2. It reaches the stratosphere due to its stability.
3. The stratosphere has an ozone layer, and we know that ozone molecules are less stable, causing them to react with fluorine and chlorine.
4. The ozone layer is then destroyed by fluoride and chlorine.
5. Fluorine and chlorine react with ozone to convert it to oxygen gas, and a single molecule of fluorine or chlorine can destroy hundreds of ozone molecules.
6. As a result of the increased use of man-made substances containing both chlorine and fluorine, the Ozone layer is depleting.
