why Hydrochloricrbon are no harm to the ozone layer mcq​

Answer 1

Ozone layer absorbs most of the sun's ultraviolet radiation (UV-B), limiting the amount of this radiation that reaches the surface of the Earth. Because this radiation causes skin cancer and cataracts, the ozone layer plays an important role in protecting human health.While HCFCs contain chlorine atoms, they are less damaging to the ozone layer because they also contain hydrogen atoms, which causes them to break down in the atmosphere faster..

Answer 2

Answer:

• Hydrofluorocarbons (HFCs) are not harm to the ozone layer because unlike CFCs they do not contain chlorine in it. But they are greenhouse gases with a high global warming potential. ... This Amendment agreed the parties to phase down HFCs production and consumption under the Montreal Protocol.
