Not all fluorocarbons contain the halogens chlorine or bromine. Only those compounds that contain chlorine or bromine can have adverse effects on ozone.
Fluorocarbons are sometimes present in the ozone layer as both chloro- and bromo- fluoridated species. Of the three halogen species present (fluorine, chlorine, and bromine) only the chlorine and bromine participate in the breakdown of ozone. Due to its stability in compounds, fluorine has no known adverse impact on ozone. Bromine is from 10 to 100 times more impactful than chlorine.
The process of ozone degradation is the release of chlorine or bromine from the source molecule by the action of sunlight. These free radicals convert ozone to oxygen and atomic oxygen. The atomic oxygen can free more chlorine or bromine. Because the CFC's are just a catalyst in the reaction, they can continue to deplete the ozone layer for some time.
Fluorocarbons, such as chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), are potent ozone-depleting substances. When released into the atmosphere, these compounds break down ozone molecules, leading to the thinning of the ozone layer. This thinning allows more harmful UV radiation from the sun to reach the Earth's surface, which can have various negative impacts on human health and the environment.
Chlorine and bromine separate from the CFCs (chlorofluorocarbons) and attack the ozone molecules, destroying them. The chlorine atom lives to destroy again.

What does fluorocarbons as propellants in aerosol cans do to ozone layer?
Fluorocarbons as propellants in aerosol cans contain chlorine and can deplete the ozone layer when released into the atmosphere. The chlorine atoms from the fluorocarbons can break down ozone molecules in the stratosphere, leading to thinning of the ozone layer and increased exposure to harmful UV radiation. This can have detrimental effects on human health and the environment.
What is the name of the chemical compounds that are destroying the ozone layer?
The chemical compounds that are destroying ozone are CFC. They can be said as Chloro Fluorocarbons.
What is the environmentally unfriendly component of chlorinated fluorocarbons that ultimately damages ozone?
The chlorine atom in chlorinated fluorocarbons is the environmentally unfriendly component that damages the ozone layer. When these compounds are released into the atmosphere, the chlorine atoms can catalyze the breakdown of ozone molecules, leading to ozone depletion.
Can canned air give you cancer?
There's no research showing that canned air directly gives you cancer. However some of the chemicals used in canned air, like fluorocarbons and halons, are known to have ill effects on the ozone. The ozone layer is the layer that protects the earth from ultraviolet rays that cause skin cancer.
Which layer absorbs ozone?
The stratosphere is the layer of the atmosphere that contains the ozone layer. Ozone absorbs most of the sun's harmful ultraviolet (UV) radiation in the stratosphere, shielding the Earth's surface from its damaging effects.
What does fluorocarbons as propellants in aerosol cans do to ozone layer?
Fluorocarbons as propellants in aerosol cans contain chlorine and can deplete the ozone layer when released into the atmosphere. The chlorine atoms from the fluorocarbons can break down ozone molecules in the stratosphere, leading to thinning of the ozone layer and increased exposure to harmful UV radiation. This can have detrimental effects on human health and the environment.
Can fluorocarbons and catalysts help fix the ozone layer?
No,, they can't. They destroy the ozone.
What layer of the atmosphere is most affected by fluorocarbons?
The ozone layer in the stratosphere is most affected by fluorocarbons. These chemicals can release chlorine and bromine atoms when they break down, which can then destroy ozone molecules, leading to ozone depletion.
How do fluorocarbons effect the the environment and air quality?
fluorocarbons affect the air quality by destroying the air molecules in the ozone layer
What are the affects of flurocarbons on the ozone layer?
Fluorocarbons contain the element fluorine. It participates in reacting with ozone and depleting it.
What is the name of the chemical compounds that are destroying the ozone layer?
The chemical compounds that are destroying ozone are CFC. They can be said as Chloro Fluorocarbons.
What is the environmentally unfriendly component of chlorinated fluorocarbons that ultimately damages ozone?
The chlorine atom in chlorinated fluorocarbons is the environmentally unfriendly component that damages the ozone layer. When these compounds are released into the atmosphere, the chlorine atoms can catalyze the breakdown of ozone molecules, leading to ozone depletion.
Why are fluorocarbons banned from the world?
Fluorocarbons, such as CFCs and HCFCs, are banned due to their damaging effect on the ozone layer, which protects Earth from harmful UV radiation. These chemicals were found to deplete the ozone layer, leading to increased risks of skin cancer, cataracts, and disruption of ecosystems. The Montreal Protocol in 1987 was established to phase out the production and use of these substances, leading to the widespread ban of fluorocarbons.
Chemicals succeeded in reducing the damage to the ozone layer?
Hydro Chloro Fluorocarbons are the alternate to CFC's. They cause much less pollution and ozone depletion than the latter.
Can canned air give you cancer?
There's no research showing that canned air directly gives you cancer. However some of the chemicals used in canned air, like fluorocarbons and halons, are known to have ill effects on the ozone. The ozone layer is the layer that protects the earth from ultraviolet rays that cause skin cancer.
What problems do CFCs cause?
Chloro-fluorocarbons damage the Earth's ozone layer, which results in a dangerous increase in the solar ultraviolet radiation which reaches the ground.
Explain the effects of cfc's on the ozone layer?
It breaks down ozone and have made parts of the ozone layer to weaken .
