    Cations are positively (+) charged ions while anions are negatively (−) charged. This can be remembered with the help of the following mnemonics. Cats have paws ⇔ Cations are pawsitive. [27] Ca+ion: The letter t in cation looks like a + (plus) sign. [28] An anion is a negative ion. (An egative ion ⇒ Anion). [29]

    formula of a carboxylate ion Salts of carboxylic acids are named following the usual cation -then- anion conventions used for ionic compounds in both IUPAC and common nomenclature systems. The name of the carboxylate anion ( R−C(=O)O − ) is derived from that of the parent acid by replacing the "–oic acid" ending with "–oate" or ...

  4. Halogenated ether - Wikipedia

    en.wikipedia.org/wiki/Halogenated_ether

    An example of an ether is the solvent diethyl ether. [1] Halogenated ethers differ from other ethers because there are one or more halogen atoms—fluorine, chlorine, bromine, or iodine—as substituents on the carbon groups. . [2] Examples of commonly used halogenated ethers include isoflurane, sevofluorane and desflurane. [3]

    A cyclic ether and high-boiling solvent (b.p. 101.1 °C). Tetrahydrofuran (THF) A cyclic ether, one of the most polar simple ethers that is used as a solvent. Anisole (methoxybenzene) An aryl ether and a major constituent of the essential oil of anise seed. Crown ethers: Cyclic polyethers that are used as phase transfer catalysts. Polyethylene ...

    Basic IUPAC inorganic nomenclature has two main parts: the cation and the anion. The cation is the name for the positively charged ion and the anion is the name for the negatively charged ion. [14] An example of IUPAC nomenclature of inorganic chemistry is potassium chlorate (KClO 3): Potassium chlorate "Potassium" is the cation name.

    Nomenclature of Inorganic Chemistry, IUPAC Recommendations 2005 is the 2005 version of Nomenclature of Inorganic Chemistry (which is informally called the Red Book). It is a collection of rules for naming inorganic compounds, as recommended by the International Union of Pure and Applied Chemistry (IUPAC).

    If they are used at all, context should clarify (disambiguate) into the 1–18 numbering. Care should be taken when translating old sources that use this nomenclature to modern terminology. Some sets of groups have names: The main group elements are the elements of groups 1, 2, and 13–18 (i.e. the s-block and p-block). [5]

  9. Polyatomic ion - Wikipedia

    en.wikipedia.org/wiki/Polyatomic_ion

    In contrast, an ammonium ion consists of one nitrogen atom and four hydrogen atoms, with a charge of +1; its chemical formula is N H + 4. Polyatomic ions often are useful in the context of acid–base chemistry and in the formation of salts. Often, a polyatomic ion can be considered as the conjugate acid or base of a neutral molecule.
