    en.wikipedia.org/wiki/List_of_phylogenetics_software

    List of phylogenetics software. This list of phylogenetics software is a compilation of computational phylogenetics software used to produce phylogenetic trees. Such tools are commonly used in comparative genomics, cladistics, and bioinformatics. Methods for estimating phylogenies include neighbor-joining, maximum parsimony (also simply ...

  4. Free-radical halogenation - Wikipedia

    en.wikipedia.org/wiki/Free-radical_halogenation

    Free-radical halogenation. In organic chemistry, free-radical halogenation is a type of halogenation. This chemical reaction is typical of alkanes and alkyl -substituted aromatics under application of UV light. The reaction is used for the industrial synthesis of chloroform (CHCl 3 ), dichloromethane (CH 2 Cl 2 ), and hexachlorobutadiene.

  5. Halogen bond - Wikipedia

    en.wikipedia.org/wiki/Halogen_bond

    Definition. Halogen bond in complex between iodine monochloride and trimethylamine. Halogen bonds occur when a halogen atom is electrostatically attracted to a partial negative charge. Necessarily, the atom must be covalently bonded in an antipodal σ-bond; the electron concentration associated with that bond leaves a positively charged "hole ...

  6. Halogen - Wikipedia

    en.wikipedia.org/wiki/Halogen

    In the modern IUPAC nomenclature, this group is known as group 17. [5] The word "halogen" means "salt former" or "salt maker". When halogens react with metals, they produce a wide range of salts, including calcium fluoride, sodium chloride (common table salt), silver bromide and potassium iodide.

  7. Halogenated ether - Wikipedia

    en.wikipedia.org/wiki/Halogenated_ether

    Structural formula of isoflurane, a typical halogenated ether. The C—O—C (carbon-oxygen-carbon) in the center is the ether group and the Cl (chlorine) and F (fluorine) are the halogen atoms, which have been substituted for all but two H (hydrogen) atoms. A halogenated ether is a subcategory of a larger group of chemicals known as ethers.

  8. Halogenation - Wikipedia

    en.wikipedia.org/wiki/Halogenation

    Halogenation. In chemistry, halogenation is a chemical reaction which introduces of 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 ...

  9. Dehalogenation - Wikipedia

    en.wikipedia.org/wiki/Dehalogenation

    Dehalogenation. In organic chemistry, dehalogenation is a set of chemical reactions that involve the cleavage of carbon - halogen bonds; as such, it is the inverse reaction of halogenation. Dehalogenations come in many varieties, including defluorination (removal of fluorine ), dechlorination (removal of chlorine ), debromination (removal of ...
