How do you go from the chemical name of a chlorofluorocarbon to its name using the word Freon?
Kavenpg
From physchem.ox.ac.uk (see link to the left):
"The naming system for Freons (chlorofluorocarbons or CFCs) was developed by Du Pont. An individual CFC is given a number determined from its structural formula, so that, for example, trichlorofluoromethane is known as Freon-11 or CFC-11.
The number is "decoded" in the following fashion: 1) Add 90 to the Freon number to give a three digit value
2a) the leftmost digit is now the number of carbon atoms,
2b) the middle digit is the number of hydrogen atoms,
2c) the rightmost digit is the number of fluorine atoms
3) all remaining atoms are chlorine"

What is chemical name of cfc?
CFC is an abbreviation for the class of chemical compounds known as Chloro-Fluoro-Carbons.
What is the origin of the word freon?
Freon is DuPont's trade name for its odorless, colorless, nonflammable, and noncorrosive chlorofluorocarbon and hydrochlorofluorocarbon refrigerants. In 1928, Thomas Midgley, Jr. aided by Charles Franklin Kettering invented a "miracle compound" called Freon. Freon represents several different chlorofluorocarbons, or CFCs, which are used in commerce and industry.
What are the products of clourofluorocarbon?
CFC, chlorofluorocarbon. has been used primarily as a refrigerate under the brand name Freon. But they were also employed as a fumigant, in fire fighting equipment and as a propellant in aerosol cans.
What is the chemical name when freon is heated and breaks down?
This is a thermal decomposition.
What is freon 12?
Dichlorodifluoromethane (R-12), usually sold under the DuPont brand name Freon-12, is a chlorofluorocarbon halomethane, commonly known as CFC, used as a refrigerant and aerosol spray propellant. Its manufacture was banned in the United States and many countries in 1994 over concerns about damage that such compounds might do to the ozone layer if released into the atmosphere.

What is the chemical name for freon?
Chlorodifluoromethane CHClF2(R-22 or HCFC-22), a type of Freon.[6][7] Dichlorodifluoromethane CCl2F2(R-12 or CFC-12), the most commonly used Freon brand refrigerant prior to its ban in many countries in 1996 and total ban in 2010. 1,1,1,2-Tetrafluoroethane CF3CH2F (R-134a or HFC-134a), one of the main replacements for the formerly widespread R-12. Freon is a rade name formed by the Chemours Co.
What is the element that composes the chlorofluorocarbon?
As the name suggests, they are made from combinations of chlorine, fluorine and carbon atoms.

Source: wikipedia as a 'freon wiki' search in Google (0.08 seconds)Freon is DuPont's trade name for its odorless, colorless, nonflammable, and noncorrosive chlorofluorocarbon and hydrochlorofluorocarbon refrigerants, which are used in air conditioning and refrigeration systems. Freon was initially developed in the early 20th century as an alternative to the toxic gases that were previously used as refrigerants, such as ammonia, chloromethane, and sulfur dioxide. Freon, in this case dichlorodifluoromethane, was invented by Thomas Midgley, Jr. with co-inventor Charles Kettering.[1] Each Freon product is designated by a number; for instance, Freon-11 is trichlorofluoromethane, while Freon-12 is dichlorodifluoromethane. In the 1990s, most uses of Freon were phased out due to the negative effects that chlorofluorocarbons and hydrochlorofluorocarbons have on the Earth's ozone layer.Thus, Freon has not been used in auto A/C's since the mid 90's. The current refrigerant used is R-134a (NOT Freon, although people may casually and incorrectly refer to it as such).In case you're curious, the DuPont trade name for R-134a is Suva.
Is freon used for air conditioning?
freon is just a brand name
How do you spell free-on?
The volatizing chemical used in mechanical refrigeration is spelled freon. This is actually the trademarked brand name (Freon) for chlorofluorocarbons (CFCs) produced by the DuPont company, but it has become a widely-used term for such refrigerants (a useful generic term).
