Bromochlorofluoromethane or fluorochlorobromomethane, is a chemical compound and trihalomethane derivative with the chemical formula C H Br Cl F. As one of the simplest possible stable chiral compounds, it is useful for fundamental research into this area of chemistry. [ 1 ]
Bromochlorodifluoromethane (BCF), also referred to by the code numbers Halon 1211 and Freon 12B1, is a haloalkane with the chemical formula C F 2 Cl Br. It is used for fire suppression, especially for expensive equipment or items that could be damaged by the residue from other types of extinguishers. [1]
Overview. This compound can be seen as a methane molecule, whose four hydrogen atoms are each replaced with a different halogen atom. As the mirror images of this molecule are not superimposable, the molecule has two enantiomers. As one of the simplest such molecules, it is often cited as the prototypical chiral compound. [2]
Trihalomethane. In chemistry, trihalomethanes (THM s) are chemical compounds in which three of the four hydrogen atoms of methane (CH4) are replaced by halogen atoms. Trihalomethanes with all the same halogen atoms are called haloforms. Many trihalomethanes find uses in industry as solvents or refrigerants.
Bromofluoromethane is an important reagent in the manufacture of intermediates, pharmaceuticals and other chemicals. Usage of bromofluoromethane is regulated due to its ozone depletion potential (0.73). Its isotopomer CH 2 Br 18 F contains fluorine-18 (18 F) and is used in radiochemistry.
Bromochloromethane or methylene bromochloride and Halon 1011 is a mixed halomethane. It is a heavy low-viscosity liquid with refractive index 1.4808. Halon 1011 was invented for use in fire extinguishers in Germany during the mid-1940s, in an attempt to create a less toxic, more effective alternative to carbon tetrachloride.
Chlorofluoromethane or Freon 31 is the hydrochlorofluorocarbon (HCFC) with the formula CH 2 ClF. It is a colorless, odorless, flammable gas. [1] It is a class II ozone depleting substance and in accordance with the montreal protocol, its production and import were banned on 1 January 2015. [2]
Isomer. In chemistry, isomers are molecules or polyatomic ions with identical molecular formula – that is, the same number of atoms of each element – but distinct arrangements of atoms in space. [1] Isomerism refers to the existence or possibility of isomers.
