  2. Ammonium - Wikipedia

    en.wikipedia.org/wiki/Ammonium

    The hydrogen atoms in the ammonium ion can be substituted with an alkyl group or some other organic group to form a substituted ammonium ion (IUPAC nomenclature: aminium ion). Depending on the number of organic groups, the ammonium cation is called a primary, secondary, tertiary, or quaternary. Except the quaternary ammonium cations, the ...

  3. Quaternary ammonium cation - Wikipedia

    en.wikipedia.org/wiki/Quaternary_ammonium_cation

    Quaternary ammonium cation. The R groups may be the same or different alkyl or aryl groups. Also, the R groups may be connected. In organic chemistry, quaternary ammonium cations, also known as quats, are positively-charged polyatomic ions of the structure [NR 4] +, where R is an alkyl group, an aryl group [1] or organyl group.

  4. Alkylammonium - Wikipedia

    en.wikipedia.org/wiki/Alkylammonium

    In organic chemistry, alkylammonium refers to cations of the formula [R 4−n NH n] +, where R = alkyl and 1≤ n ≤ 4. The cations with four alkyl substituents, i.e., [R 4 N] +, are further classified as quaternary ammonium cations and are discussed more thoroughly in the article with that title.

  5. Alkyl group - Wikipedia

    en.wikipedia.org/wiki/Alkyl_group

    A cycloalkyl group is derived from a cycloalkane by removal of a hydrogen atom from a ring and has the general formula −C n H 2n−1. [2] Typically an alkyl is a part of a larger molecule. In structural formulae, the symbol R is used to designate a generic (unspecified) alkyl group. The smallest alkyl group is methyl, with the formula −CH 3 ...

  6. Benzalkonium chloride - Wikipedia

    en.wikipedia.org/wiki/Benzalkonium_chloride

    It is an organic salt classified as a quaternary ammonium compound. ADBACs have three main categories of use: as a biocide, a cationic surfactant, and a phase transfer agent. [2] ADBACs are a mixture of alkylbenzyldimethylammonium chlorides, in which the alkyl group has various even-numbered alkyl chain lengths.

  7. Amine - Wikipedia

    en.wikipedia.org/wiki/Amine

    Amine. In chemistry, amines (/ ə ˈ m iː n, ˈ æ m iː n /, [1] [2] UK also / ˈ eɪ m iː n / [3]) are compounds and functional groups that contain a basic nitrogen atom with a lone pair.Formally, amines are derivatives of ammonia (NH 3 (in which the bond angle between the nitrogen and hydrogen is 107°), wherein one or more hydrogen atoms have been replaced by a substituent such as an ...

    Quaternary ammonium compounds are positively charged polyatomic ions of the structure NR 4 + with R being alkyl or aryl groups. The R groups may also be connected. The R groups may also be connected. Wikimedia Commons has media related to Quaternary ammonium compounds .

  9. Metal ammine complex - Wikipedia

    en.wikipedia.org/wiki/Metal_ammine_complex

    "Ammine" is spelled this way for historical reasons; [1] in contrast, alkyl or aryl bearing ligands are spelt with a single "m". Almost all metal ions bind ammonia as a ligand, but the most prevalent examples of ammine complexes are for Cr(III), Co(III), Ni(II), Cu(II) as well as several platinum group metals. [2]
