What is chlorofluorocarbons in simple terms?
: any of several simple gaseous compounds that contain carbon, chlorine, fluorine, and sometimes hydrogen, that are used as refrigerants, cleaning solvents, and aerosol propellants and in the manufacture of plastic foams, and that are believed to be a major cause of stratospheric ozone depletion —abbreviation CFC.
What are chlorofluorocarbons quizlet?
chlorofluorocarbons (CFCs) Organic compounds made up of atoms of carbon, chlorine, and fluorine. An example is Freon-12 (CCl2F2), used as a refrigerant in refrigerators and air conditioners and in making plastics such as Styrofoam.
What is ozone layer?
The ozone layer is the common term for the high concentration of ozone that is found in the stratosphere around 15–30km above the earth’s surface. It covers the entire planet and protects life on earth by absorbing harmful ultraviolet-B (UV-B) radiation from the sun.
What are examples of chlorofluorocarbons?
Chlorofluorocarbons are refrigerants that contain chlorine. They have been banned since the beginning of the 90’s because of their negative environmental impacts. Examples of CFCs are R11, R12 and R115. The conversion of equipment and systems using CFCs has not yet been completed.

Where does chlorofluorocarbons come from?
The most common source of CFCs are refrigerants, but fire suppression systems for aircraft and aerosols also emit CFCs into the atmosphere.
Which is the best definition of chlorofluorocarbon?
Definition of chlorofluorocarbon. : any of several simple gaseous compounds that contain carbon, chlorine, fluorine, and sometimes hydrogen, that are used as refrigerants, cleaning solvents, and aerosol propellants and in the manufacture of plastic foams, and that are believed to be a major cause of stratospheric ozone depletion —abbreviation CFC.
Why are chlorofluorocarbons banned in the world?
Why were CFCs banned? Ans. Chlorofluorocarbons (CFCs) are a group of odourless manufactured chemicals. Because they damage the earth’s ozone layer, CFCs have been banned since 1996. Depletion of the Ozone Layer will have a negative impact on the biodiversity of the earth itself.
When was the chlorofluorocarbon ( CFC ) chemical compound invented?
Corrosionpedia explains Chlorofluorocarbon (CFC) Chlorofluorocarbons are chemical compounds that were developed commercially in the 1930s by DuPont.
What is the difference between chlorofluorocarbons and HCFCs?
For other singular uses, see CFC (disambiguation). Chlorofluorocarbons ( CFCs) and hydrochlorofluorocarbons ( HCFCs) are fully or partly halogenated paraffin hydrocarbons that contain only carbon (C), hydrogen (H), chlorine (Cl), and fluorine (F), produced as volatile derivative of methane, ethane, and propane.
