Depletion of ozone layer by CFCs is mainly due to formation of​

Answer 1

Explanation:

CFCs are said to be the major culprit in the depletion of ozone layer.

This is due to the fact that CFCs go in the ozone layer and break the bond between chlorine and carbon atoms.

When this bond in broken, chlorine reacts with ozone (03) and extracts oxygen leaving behind free oxygen radicals.

This way ozone gets depleted.

A single CFC molecule can destroy 100,000 ozone molecules.

Answer 2

the chlorofluorocarbon is one of the most harmful compound as it leads to the destruction of the ozone layer present in the stratosphere and allows the harmful ultraviolet rays from the sun to reach the earth.

Explanation:

• Chlorofluorocarbon breaks down into to chlorine fluorine and carbon with the help of conversion of ozone into oxygen. two molecules of ozone breaks down to form three molecules of oxygen.

• Chlorofluorocarbon is released from refrigerators aerosol sprays and from air conditioners.

• The molecules of ozone then settles down. one molecule of chlorofluorocarbon is sufficient to breakdown around 50000 molecules of  ozone.
