2-Chloro-1,1,1-trifluoroethane, also known as 1,1,1-trifluoro-2-chloroethane or Freon 133a, is an alkyl halide belonging to the category of hydrochlorofluorocarbons, having chemical formula F 3 C-CH 2-Cl. Under standard conditions, it appears as a colorless gas, partially soluble in water.
For example, R-22 has one carbon atom, one hydrogen atom (2−1 = 1), two fluorine atoms, and one chlorine atom (4−2−1 = 1), so it is chlorodifluoromethane, while R-134 has two carbon atoms (2−1 = 1), two hydrogen atoms (3−1 = 2), four fluorine atoms, and no chlorine atoms (6−2−4 = 0), so it is one of the tetrafluoroethanes. This ...
Chlorotrifluoroethylene is produced commercially by the dechlorination of 1,1,2-trichloro-1,2,2-trifluoroethane with zinc: [3]. CFCl 2-CF 2 Cl + Zn → CClF=CF 2 + ZnCl 2. In 2012, an estimated 1–10 million pounds were produced commercially in the United States.
1,1,2-Trichloro-1,2,2-trifluoroethane, also called trichlorotrifluoroethane (often abbreviated as TCTFE) or CFC-113, is a chlorofluorocarbon. It has the formula Cl 2 FC−CClF 2 . This colorless, volatile liquid is a versatile solvent.
Between 2012 and 2017, concentrations of the gas jumped by 40 percent. [5] In 2020, the global mean concentration of CFC-113a was 1.02 parts per trillion with global emissions of 2.5 ± 0.4 ODP-Gg yr −1. [6]

An easy example is that of CFC-12, which gives: 90+12=102 -> 1 carbon, 0 hydrogens, 2 fluorine atoms, and hence 2 chlorine atoms resulting in CCl 2 F 2. The main advantage of this method of deducing the molecular composition in comparison with the method described in the paragraph above is that it gives the number of carbon atoms of the molecule.
