Chlorofluorocarbons nomenclature

When some of the chlorines are replaced by hydrogens, CFCs become HCFCs, the now more common nomenclature for those chlorofluorocarbons containing hydrogen. The numbering is the same. When more than one isomer is possible, the most symmetrically substituted compound has only a number letters a and b are added to designate less symmetrical isomers. 

For a discussion of the numerical nomenclature applied to this aerosol propellant, see Chlorofluorocarbons. 

What are the chemical and physical properties of chlorofluorocarbons Describe the CFC nomenclature. 

While imperfect, the halocarbon nomenclature system enables the simpler halocarbon structures to be relatively well described in a few characters a letter indicating the chlorofluorocarbon s use (although R, for refrigerant, is used ubiquitously) followed by ABCD ...
