From the presence of the element fluorine, the molecules are spelled chlorofluorocarbons (CFCs).
(*fluorine shares this "UO" spelling with the words fluorescent and fluorescence)
CFCs
it is commonly known as freon.
They come from various sources. AC's, deodorants etc are some examples.
CFC's react with ozone. They decompose it to deplete the layer.
The propellant is usually Butane, which took over from ChloroFlourocarbons, to save the ozone layer.
CFC's are very reactive chemicals. They react with ozone to decompose it and deplete it.
United States is the lead producer of CFC's. These deplete the ozone layer.
Carbon dioxide, methane, nitrogen oxide, chloroflourocarbons
Yes, CFCs can destroy the ozone layer. They react with ozone present in ozone layer and decompose it.
CFC's may be harming the ozone layer. They do it by depleting the ozone, decomposing into single atoms.
There are many gases that cause "greenhouse effects". Water Vapour Carbon dioxide Methane Nitrous Oxide Ozone Chloroflourocarbons (CFC's) are just a few.
The various CFC's and the H CFC's are the ones which contribute maximum to the ozone depletion.
