What is the formula of chlorofluorocarbon?
CFCs are halocarbons that contain only the elements carbon, chlorine, and fluorine. The most common CFCs are small molecules containing only one or two carbon atoms. For example, a common refrigerant has the chemical formula of CCl2 F2 , which in industry-invented shorthand is known as CFC-12.

What do you mean by CFC-11?
Trichlorofluoromethane, also called freon-11, CFC-11, or R-11, is a chlorofluorocarbon (CFC). It is a colorless, faintly ethereal, and sweetish-smelling liquid that boils around room temperature. CFC-11 is a Class 1 ozone-depleting substance which damages Earth’s protective stratospheric ozone layer.

What is a CFC refrigerant?
CFC Refrigerant: CFC refers to the chemical composition of the refrigerant. Chlorofluorocarbon indicates that the refrigerant is comprised of Chlorine, Fluorine, and Carbon. Common CFC refrigerants are R-11, R-12, R-13, R-113, R-114, and R-115.
What is R12 refrigerant?
R-12 is a colorless and odorless CFC refrigerant that was completely banned from production by 1996 under the Montreal Protocol for depleting the ozone. R-12 has many applications in refrigeration and air conditioning including large to mediums size chillers, automotive air conditioning, and as an aerosol propellant.
Is r11 banned?
R-11 is a colorless and odorless CFC refrigerant that was completely banned from production by 1996 under the Montreal Protocol for depleting the ozone. It is a low-pressure refrigerant that was commonly used in centrifugal chillers and before the 1970’s it was used as a propellant for aerosols.
Do we still have a hole in the ozone layer?
While the 2021 Antarctic ozone hole is larger than average, it is substantially smaller than those in the late 1990s and early 2000s. … The ozone hole is recovering due to the Montreal Protocol and subsequent amendments banning the release of harmful ozone-depleting chemicals called chlorofluorocarbons, or CFCs.
What is the Montreal Protocol?
The Montreal Protocol, finalized in 1987, is a global agreement to protect the stratospheric ozone layer by phasing out the production and consumption of ozone-depleting substances (ODS). … The United States ratified the Montreal Protocol in 1988 and has joined four subsequent amendments.
How CFC is released from refrigerator?
CFC starts out as a liquid. The pump pushes the CFC through a series of coils in the freezer area. There the chemical turns to a vapour. … Modern refrigerators don’t use CFCs because they are harmful to the atmosphere if released.
Is CFC banned in India?
Under the Montreal Protocol, to which India became a signatory in 1992, CFCs have to phased out in India and the developing world by 2010 and there are indications this deadline will be advanced by 4 years. Of all the substances banned by the Montreal Protocol, India currently produces and uses only seven.
What is the difference between chlorofluorocarbons and hydrofluorocarbons?
The key difference between CFC and HCFC is that the CFC contains only carbon, fluorine and chlorine atoms whereas HCFC contains hydrogen, carbon, fluorine and chlorine atoms. More importantly, CFC causes serious ozone depletion but HCFC, comparatively, has a much lesser impact on the ozone layer.
How many chlorine atoms are in CFCs?
So the chemical formula for CFC-11 is CFCl3. That is, it has 1 carbon atom, no hydrogen, 1 fluorine atom, and 3 chlorine atoms.
What are examples of CFCs quizlet?
(CFC) Organic compounds made up of atoms of carbon, chlorine, and fluorine. An example is Freon -12 (CCl2F2), which is used as a refrigerant in refrigerators and air conditioners and in making plastics such as Styrofoam.
Is chlorine a CFC?
chlorofluorocarbon (CFC), any of several organic compounds composed of carbon, fluorine, and chlorine. When CFCs also contain hydrogen in place of one or more chlorines, they are called hydrochlorofluorocarbons, or HCFCs. CFCs are also called Freons, a trademark of the E.I.
Which of the following refrigerant contains chlorine?
