In secondary (2°) haloalkanes, the carbon that carries the halogen atom has two C–C bonds. In tertiary (3°) haloalkanes, the carbon that carries the halogen atom has three C–C bonds. [citation needed] Haloalkanes can also be classified according to the type of halogen on group 17 responding to a specific halogenoalkane.
Halocarbon compounds are chemical compounds in which one or more carbon atoms are linked by covalent bonds with one or more halogen atoms (fluorine, chlorine, bromine or iodine – group 17) resulting in the formation of organofluorine compounds, organochlorine compounds, organobromine compounds, and organoiodine compounds.
The following is a list of straight-chain alkanes, the total number of isomers of each (including branched chains), and their common names, sorted by number of carbon atoms. [ 1 ] [ 2 ] Number of C atoms
A carbon–carbon double bond consists of a sigma bond and a pi bond. This double bond is stronger than a single covalent bond (611 kJ/mol for C=C vs. 347 kJ/mol for C–C), [1] but not twice as strong. Double bonds are shorter than single bonds with an average bond length of 1.33 Å (133 pm) vs 1.53 Å for a typical C-C single bond. [7]
Two groups of haloalkanes, hydrofluorocarbons (HFCs) and perfluorocarbons, are targets of the Kyoto Protocol. [8] Allan Thornton, President of the Environmental Investigation Agency, a non-governmental, environmental watchdog, says that HFCs are up to 12,500 times as potent as carbon dioxide in global warming.

Haloalkane, or halogenoalkane, a group of chemical compounds consisting of alkanes with linked halogens (in particular, bromine-containing haloalkanes) Halomethane compounds: Halon 10001 (iodomethane) Halon 1001 (bromomethane) Halon 1011 (bromochloromethane, CH 2 BrCl) Halon 104 (carbon tetrachloride) Halon 1103 (tribromofluoromethane)
2-Chloro-1,1-difluoroethane (HCFC-142) is a haloalkane and a hydrochlorofluorocarbon. It is produced as a byproduct of the production of 1-chloro-1,1-difluoroethane (HCFC-142b). [1] According to a 2022 report by the WMO and other agencies, it has an ODP of 0.019 and a 100-year GWP of 189. [2]: Table A-5
A hydrohalogenation reaction is the electrophilic addition of hydrogen halides like hydrogen chloride or hydrogen bromide to alkenes to yield the corresponding haloalkanes. [ 1 ] [ 2 ] [ 3 ] If the two carbon atoms at the double bond are linked to a different number of hydrogen atoms, the halogen is found preferentially at the carbon with fewer ...
