    en.wikipedia.org/wiki/Halogen

    The halogens (/ ˈ h æ l ə dʒ ə n, ˈ h eɪ-,-l oʊ-,-ˌ dʒ ɛ n / [1] [2] [3]) are a group in the periodic table consisting of six chemically related elements: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and the radioactive elements astatine (At) and tennessine (Ts), though some authors [4] would exclude tennessine as its chemistry is unknown and is theoretically expected to ...

    en.wikipedia.org/wiki/Halocarbon

    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.

  7. Halogenation - Wikipedia

    en.wikipedia.org/wiki/Halogenation

    In chemistry, halogenation is a chemical reaction which introduces one or more halogens into a chemical compound. Halide-containing compounds are pervasive, making this type of transformation important, e.g. in the production of polymers, drugs. [1] This kind of conversion is in fact so common that a comprehensive overview is challenging.

  8. Trihalomethane - Wikipedia

    en.wikipedia.org/wiki/Trihalomethane

    In chemistry, trihalomethanes (THMs) are chemical compounds in which three of the four hydrogen atoms of methane (CH 4) 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.

  9. Pseudohalogen - Wikipedia

    en.wikipedia.org/wiki/Pseudohalogen

    Examples of symmetrical pseudohalogen compounds (Ps−Ps, where Ps is a pseudohalogen) include cyanogen (CN) 2, thiocyanogen (SCN) 2 and hydrogen peroxide H 2 O 2. Another complex symmetrical pseudohalogen compound is dicobalt octacarbonyl, Co 2 (CO) 8. This substance can be considered as a dimer of the hypothetical cobalt tetracarbonyl, Co(CO) 4.
