Detailed explanation-1: -Gaseous CFCs can deplete the ozone layer when they slowly rise into the stratosphere, are broken down by strong ultraviolet radiation, release chlorine atoms, and then react with ozone molecules. See Ozone Depleting Substance.)
Detailed explanation-2: -Ozone-depleting substances are industrial compounds – such as chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) – which diminish stratospheric ozone. ODS refrigerants are used in cooling mechanisms such as air conditioners or refrigerators.
Detailed explanation-3: -An example of a refrigerant CFC is dichlorodifluoromethane, CF2Cl2 (also known as CFC-12), which boils at-30°C. Another once-common CFC is trichlorofluoromethane, CFCl3 (CFC-11), which boils at 24°C and was once the propellant in around half of all the aerosol cans used in the world.
Detailed explanation-4: -Chlorofluorocarbons (CFCs) are a group of odourless manufactured chemicals. Because they damage the earth’s ozone layer, CFCs have been banned since 1996. Depletion of the Ozone Layer will have a negative impact on the biodiversity of the earth itself.
