  2. Acid anhydride - Wikipedia

    en.wikipedia.org/wiki/Acid_anhydride

    Organic acid anhydrides often form when one equivalent of water is removed from two equivalents of an organic acid in a dehydration reaction. In inorganic chemistry, an acid anhydride refers to an acidic oxide, an oxide that reacts with water to form an oxyacid (an inorganic acid that contains oxygen or carbonic acid), or with a base to form a ...

  3. IUPAC nomenclature of organic chemistry - Wikipedia

    en.wikipedia.org/wiki/IUPAC_nomenclature_of...

    Acid anhydrides (R−C(=O)−O−C(=O)−R) have two acyl groups linked by an oxygen atom. If both acyl groups are the same, then the name of the carboxylic acid with the word acid is replaced with the word anhydride and the IUPAC name consists of two words.

  4. Organic acid anhydride - Wikipedia

    en.wikipedia.org/wiki/Organic_acid_anhydride

    A common type of organic acid anhydride is a carboxylic anhydride, where the parent acid is a carboxylic acid, the formula of the anhydride being (RC(O)) 2 O. Symmetrical acid anhydrides of this type are named by replacing the word acid in the name of the parent carboxylic acid by the word anhydride. [2] Thus, (CH 3 CO) 2 O is called acetic ...

  5. Acetic anhydride - Wikipedia

    en.wikipedia.org/wiki/Acetic_anhydride

    Acetic anhydride, or ethanoic anhydride, is the chemical compound with the formula (CH 3 CO) 2 O. Commonly abbreviated Ac 2 O, it is the simplest isolable anhydride of a carboxylic acid and is widely used as a reagent in organic synthesis. It is a colorless liquid that smells strongly of acetic acid, which is formed by its reaction with ...

  6. Isobutyric anhydride - Wikipedia

    en.wikipedia.org/wiki/Isobutyric_anhydride

    Isobutyric anhydride is an organic compound with the formula ((CH 3) 2 CHCO) 2 O. It is an acyclic carboxylic anhydride of isobutyric acid. [2] It is classified as an organic acid anhydride, being derived from dehydration of isobutyric acid. It is a colorless liquid with a strong, pungent odor. [3] [4]

    The main structure of chemical names according to IUPAC nomenclature. IUPAC nomenclature is a set of recommendations for naming chemical compounds and for describing chemistry and biochemistry in general. The International Union of Pure and Applied Chemistry (IUPAC) is the international authority on chemical nomenclature and terminology.
