What characteristic(s) of CFCs make them more likely to reach the stratosphere than most other compounds containing chlorine?
CFC's are heavier than air and contain chlorine thus they would be part of the group of chemicals in question. In theory most items heavier than air should not be able to reach high altitudes, although very small amounts of this gas have been found in the stratosphere.
CFCs are attracted to ultraviolet radiation
they are very stable

Each chlorine atom in the stratosphere can destroy how many ozone molecules?
Each chlorine atom in the stratosphere can destroy thousands of ozone molecules, with estimates ranging from about 100,000 to over a million ozone molecules before it is removed from the atmosphere. This destructive potential is primarily due to the catalytic cycle that chlorine undergoes when it reacts with ozone (O₃), leading to its depletion. The significant impact of chlorine on ozone levels is a key reason for international efforts to reduce chlorine-containing compounds, such as chlorofluorocarbons (CFCs).
How are chlorine free radicals are formed in the upper atmosphere?
In the upper atmosphere, ultraviolet (UV) radiation breaks apart chlorine-containing compounds like chlorofluorocarbons (CFCs). This process releases chlorine free radicals, which then participate in ozone-depleting reactions. The resulting chlorine free radicals can catalytically destroy ozone molecules in the stratosphere.
What characteristics of CFC make it to the stratosphere?
Chlorofluorocarbons (CFCs) are stable and non-reactive compounds, which allows them to persist in the lower atmosphere for a long time before reaching the stratosphere. Their low volatility and high molecular weight enable them to slowly rise through the atmosphere. Once in the stratosphere, CFCs are broken down by ultraviolet (UV) radiation, releasing chlorine atoms that contribute to ozone depletion.
What aerosols deplete ozone?
Aerosols containing chlorine and bromine compounds, such as chlorofluorocarbons (CFCs) and halons, have been identified as major contributors to ozone depletion in the stratosphere. When these compounds are released into the atmosphere, they can break down ozone molecules, leading to the thinning of the ozone layer.
What are the group of chlorine compounds that cause highest ozone depletion called?
The only chlorine-specific name is "chlorine-containing gases". They may or may not contain fluorine (chloromethane does not). They may or may not have carbon (HCl does not). The compounds are chlorofluorocarbons, bromofluorocarbons. A lot of initials get thrown around too - CFCs HCFCs. The active agents are the chlorine and bromine ions, the fluorine is too tightly bound to ionize. "Ozone Depleting Substances" or "Ozone Depleting Compounds" is the generic term, that does not limit itself to only chlorine-as-depleter.
What has the author Douglas D Davis written?
Douglas D. Davis has written: 'A kinetics investigation of several reactions involving chlorine containing compounds' -- subject(s): Atmospheric chemistry, Chlorine compounds, Stratosphere 'Supra-competitive prices and market prices in posted-offer experiments'
What percent of the sources of chlorine in the stratosphere are CFCS?
Over 80% of the chlorine found in the stratosphere comes from chlorofluorocarbons (CFCs). These compounds can break down in the upper atmosphere, releasing chlorine atoms that can then participate in ozone depletion reactions.
What does the prefix chloro- mean?
The prefix chloro- means pertaining to chlorine or compounds containing chlorine.
What environmental problem have researches connected halo carbons containing chlorine and fluorine?
Researchers have connected halocarbons containing chlorine and fluorine to the depletion of the ozone layer. These compounds, such as chlorofluorocarbons (CFCs), can release chlorine atoms that break down ozone molecules in the stratosphere, leading to a thinning of the ozone layer and increased exposure to harmful UV radiation on Earth's surface.

This process releases chlorine free radicals, which then participate in ozone-depleting reactions. The resulting chlorine free radicals can catalytically destroy ozone molecules in the stratosphere.
What are the main sources of chlorine radicals?
The main sources of chlorine radicals are reactions involving chlorine-containing compounds such as chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and volatile organic compounds (VOCs) in the atmosphere. These compounds can release chlorine radicals when broken down by sunlight or other chemical reactions.
What are compounds containing halogens called?
Compounds containing halogens are called halides. These compounds are formed when a halogen element (such as fluorine, chlorine, bromine, or iodine) reacts with another element to form a chemical bond.

What are chlorofluorocarbones?
Chlorofluorocarbons also called the CFC refer to the organic compounds containing fluorine, chlorine and carbon.
