Soft CFC's, they added hydrogen to the CFC's previously used that were called hard CFC's. By doing this it won't allow the CFC's to travel up to the stratosphere, where it breaks down the ozone. With the added hydrogen will stop it in the troposphere and combine to form compounds such as CO2 + HCl (or HF), therefore not harmful to the ozone.
Examples CH2Cl (HCFC-22) or CHCl2-CF2 (HCFC-123)
Some common CFCs used in refrigerators were R-12 (dichlorodifluoromethane) and R-22 (chlorodifluoromethane). However, most refrigerators now use HFCs (hydrofluorocarbons) such as R-134a as a more environmentally friendly alternative.
the source of cfc is mainly from refrigerators n ac's...increase in the emission of cfc may lead to a hole in the ozone layer,the result of which is harmful rays such as ultra violet rays reaching out to people which causes skin cancer
CFCs (chlorofluorocarbons) are a type of synthetic compounds that were commonly used as refrigerants, solvents, and propellants in aerosol sprays. However, their use has been largely phased out due to their harmful impact on the ozone layer, which led to the development of more environmentally friendly alternatives.
Chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) are two substances commonly used in refrigerators that are harmful for the ozone layer. These chemicals break down ozone molecules in the stratosphere, leading to ozone depletion and creating the ozone hole. It is important to use alternative refrigerants that are ozone-friendly, such as hydrofluorocarbons (HFCs).
CFC's are chlorofluorocarbons. They are made in industry for the use of refrigeration. Firstly they were thought of miracle compounds. But in 1985 everything changed when Dr. Farman and Dr. Mario Molina discovered that there is a hole in the layer of earth protecting us from the harmful UV radiation. The hole was due to these CFC's only. What these CFC's do is that are carried by westerly's to the poles. Due to the low temperature, they take polar stratospheric clouds as the base or catalysts and perform depletion. They decompose the ozone to form their oxide and that oxide again decomposes to form the original element. This is a chain reaction. A single CFC molecule can destroy over 100,000 molecules of ozone. The main sources of CFC's in day to day life are:DeodorantsAir Conditioners'Aerosol CansSpray CansVehicles Exhaust.

CFC's are mainly there in refrigerators only. They act as cooling agent i.e. they perform the main work.
Refrigerators now primarily use hydrofluorocarbons (HFCs) or hydrochlorofluorocarbons (HCFCs) as refrigerants instead of chlorofluorocarbons (CFCs). These alternatives have lower ozone depletion potential and are less harmful to the environment. Some newer refrigerators also use natural refrigerants like carbon dioxide or propane.
Nowadays we have alternatives for CFC's. These are called HCFC's.
Ozone depletion is due to CFC's. These CFC's are released from refrigerators.
I THINK there is a ban on CFC refrigerators in many countries already.
CFC's have uses in household as well. It is used in deodorant, refrigerators, air conditioners, aerosol sprays etc.
In the past the chemical CFC (chlorofluorocarbons) was used in refrigerators however a few decades ago it was phased out
Freon, specifically CFC-12, was phased out of use in new refrigerators in 1994 due to its harmful environmental impact on the ozone layer. It was replaced by more environmentally friendly refrigerants, such as HFC-134a.
People use CFC's. They react with ozone and deplete it.
