What are 3 examples of CFCs?

CFCs Examples

• Trichlorofluoromethane- a methane hydrocarbon with one-carbon compound and replacement of the hydrogens with three chlorine and one fluorine atom.
• Dichlorodifluoromethane- a colorless, slightly water-soluble, nonflammable gas.
• Dichlorotetrafluoroethane- a colorless, nearly odorless nonflammable gas.

What are common CFCs?

Numbering system

Principal CFCs
Systematic name	Common/trivial name(s), code	Formula
Trichlorofluoromethane	Freon-11, R-11, CFC-11	CCl3F
Dichlorodifluoromethane	Freon-12, R-12, CFC-12	CCl2F2
Chlorotrifluoromethane	Freon-13, R-13, CFC-13	CClF3

What is the other name of CFC-11?

Trichlorofluoromethane, also known as CFC-11 and Freon 11, is a refrigerant, aerosol propellant, and foam-blowing agent. It is unusual in that its boiling point is at normal ambient temperature and pressure, so it can be handled as a liquid or gas.

Is Freon a CFC?

Freons are CFCs with molecules having one or more hydrogen atoms replaced by halogens (chlorine and/or fluorine).

How many types of CFCs are there?

CFCs under commercial uses as refrigerants and blowing agents include trichlorofluoromethane (CFC-11), dichlorodifluoromethane (CFC-12), 1,1,2-trichloro-1,2,2-trifluoroethane (CFC-113), 1,2-dichlorotetrafluoroethane (CFC-114), and chloropentafluoroethane (CFC-115).

Is chlorine a CFC?

Chlorofluorocarbons (CFCs) are nontoxic, nonflammable chemicals containing atoms of carbon, chlorine, and fluorine. They are used in the manufacture of aerosol sprays, blowing agents for foams and packing materials, as solvents, and as refrigerants.

How are CFCs named?

CFC’s (chlorofluorocarbons) Midgley and Henne developed in 1929 a naming system for halocarbons containing carbon, hydrogen, chlorine and fluorine. Park refined the system some years later. CFC (chlorofluorocarbons) was the group name, which was later divided into sub-groups like HCFC and HFC.

What is CFC l3?

Trichlorofluoromethane is a one-carbon compound that is methane in which the hydrogens have been replaced by three chlorine and one fluorine atom. It has a role as a refrigerant and an environmental contaminant. It is a halomethane and a chlorofluorocarbon.

Is R-134a a CFC?

R134a is also known as Tetrafluoroethane (CF3CH2F) from the family of HFC refrigerant. With the discovery of the damaging effect of CFCs and HCFCs refrigerants to the ozone layer, the HFC family of refrigerant has been widely used as their replacement.

Is R-410A a CFC?

R-22, commonly known by the brand name Freon, is a chlorofluorocarbon (CFC), while R-410A is not. As National Geographic explains in their article “The Facts of Ozone Depletion,” CFCs are the chemicals most responsible for damaging the earth’s ozone layer over the past several decades.

Is R134a a CFC?

Is Freon 21 a CFC?

What is in Freon?

In addition to fluorine and carbon, Freons often contain hydrogen, chlorine, or bromine. Thus, Freons are types of chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and related compounds.

Why is it called 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.

Which refrigerants are CFCS?

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. A blend that contains a CFC and any other product is still considered a CFC refrigerant.

Which refrigerants are CFCs?

Is CFC in R-22?

Freon is DuPont’s commercial name for R22, a member of the chlorofluorocarbon (CFC) organic compounds that contains carbon, chlorine, hydrogen and fluorine.
