What are CFCs?

What are CFCs?. CFC stands for chlorofluorocarbon. CFCs are a family of compounds that contain only chlorine, fluorine and carbon atoms. Here are some examples:. CCl 2 F 2. Cl 2 FC-CClF 2. 1,1,2-trichloro-1,2,2- trifluoroethane. Dichlorodifluoromethane. Naming CFCs.

  1. What are CFCs? CFC stands for chlorofluorocarbon. CFCs are a family of compounds that contain only chlorine, fluorine and carbon atoms. Here are some examples: CCl2F2 Cl2FC-CClF2 1,1,2-trichloro-1,2,2- trifluoroethane Dichlorodifluoromethane

  2. Naming CFCs

  3. What are the properties of CFCs? CFCs contain strong covalent bonds. This means that they are very inert (unreactive). CFCs therefore last for a long time in the environment as they don’t decompose or react with other substances easily. They are also insoluble in water, and have low melting and boiling points. boiling point: –30°C melting point: –158°C boiling point: 48°C melting point: –35°C What state are these CFCs at room temperature?

  4. What are CFCs used for? During the 1930s, an American engineer named Thomas Midgely discovered that CFCs were suitable for use as coolants in refrigerators. This was a very useful discovery because the refrigerants used previously were toxic compounds like ammonia and sulfur dioxide. In the 1960s, other uses for CFCs started to be found: as propellants for aerosol cans and to inject bubbles into plastic to make foams for insulation.
