  2. Ester - Wikipedia

    en.wikipedia.org/wiki/Ester

    An ester of a carboxylic acid. R stands for any group (typically hydrogen or organyl) and R ′ stands for any organyl group. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (R ′).

    An ester of carboxylic acid. R stands for any group (organic or inorganic) and R′ stands for organyl group. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (−R).

    Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...

  5. Borate - Wikipedia

    en.wikipedia.org/wiki/Borate

    Borate ions occur, alone or with other anions, in many borate and borosilicate minerals such as borax, boracite, ulexite (boronatrocalcite) and colemanite.Borates also occur in seawater, where they make an important contribution to the absorption of low frequency sound in seawater.

  6. Moiety (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Moiety_(chemistry)

    It also contains an ester functional group (in red), and an acetyl functional group (encircled with dark green). Other divisions can be made. In organic chemistry, a moiety (/ ˈ m ɔɪ ə t i / MOY-ə-tee) is a part of a molecule [1] [2] that is given a name because it is identified as a part of other molecules as well.

  7. Carbonyl group - Wikipedia

    en.wikipedia.org/wiki/Carbonyl_group

    In organic chemistry, a carbonyl group is a functional group with the formula C=O, composed of a carbon atom double-bonded to an oxygen atom, and it is divalent at the C atom. It is common to several classes of organic compounds (such as aldehydes, ketones and carboxylic acid), as part of many larger functional groups. A compound containing a ...

  8. Sulfonate - Wikipedia

    en.wikipedia.org/wiki/Sulfonate

    Esters with the general formula R 1 SO 2 OR 2 are called sulfonic esters.Individual members of the category are named analogously to how ordinary carboxyl esters are named.For example, if the R 2 group is a methyl group and the R 1 group is a trifluoromethyl group, the resulting compound is methyl trifluoromethanesulfonate.

    en.wikipedia.org/wiki/Carboxylate

    In organic chemistry, a carboxylate is the conjugate base of a carboxylic acid, RCOO − (or RCO − 2). It is an anion , an ion with negative charge . Carboxylate salts are salts that have the general formula M(RCOO) n , where M is a metal and n is 1, 2,....
