  2. Hydroxy group - Wikipedia

    en.wikipedia.org/wiki/Hydroxy_group

    In chemistry, a hydroxy or hydroxyl group is a functional group with the chemical formula −OH and composed of one oxygen atom covalently bonded to one hydrogen atom. In organic chemistry , alcohols and carboxylic acids contain one or more hydroxy groups.

  3. Alpha hydroxycarboxylic acid - Wikipedia

    en.wikipedia.org/wiki/Alpha_hydroxycarboxylic_acid

    Alpha hydroxy carboxylic acids, or α-hydroxy carboxylic acids (AHAs), are a group of carboxylic acids featuring a hydroxy group located one carbon atom away from the acid group. This structural aspect distinguishes them from beta hydroxy acids , where the functional groups are separated by two carbon atoms. [ 1 ]

  4. Carboxylic acid - Wikipedia

    en.wikipedia.org/wiki/Carboxylic_acid

    The hydroxyl group on carboxylic acids may be replaced with a chlorine atom using thionyl chloride to give acyl chlorides. In nature, carboxylic acids are converted to thioesters. Thionyl chloride can be used to convert carboxylic acids to their corresponding acyl chlorides. First, carboxylic acid 1 attacks thionyl chloride, and chloride ion ...

  5. Phenols - Wikipedia

    en.wikipedia.org/wiki/Phenols

    The acidity of the hydroxyl group in phenols is commonly intermediate between that of aliphatic alcohols and carboxylic acids (their pK a is usually between 10 and 12). Deprotonation of a phenol forms a corresponding negative phenolate ion or phenoxide ion , and the corresponding salts are called phenolates or phenoxides ( aryloxides according ...

  6. Functional group - Wikipedia

    en.wikipedia.org/wiki/Functional_group

    Functional group interconversion can be used in retrosynthetic analysis to plan organic synthesis. A functional group is a group of atoms in a molecule with distinctive chemical properties, regardless of the other atoms in the molecule. The atoms in a functional group are linked to each other and to the rest of the molecule by covalent bonds.

  7. 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 ′).

  9. Hydroxylation - Wikipedia

    en.wikipedia.org/wiki/Hydroxylation

    (i) most commonly, hydroxylation describes a chemical process that introduces a hydroxyl group (−OH) into an organic compound. (ii) the degree of hydroxylation refers to the number of OH groups in a molecule. The pattern of hydroxylation refers to the location of hydroxy groups on a molecule or material. [1]
