  • What is an example of an organic acid anhydride?

    The common type of organic acid anhydride is Carboxylic Anhydride, where the parent acid is a carboxylic acid, with an anhydride formula (RC(O))2O. These types of symmetrical acid anhydrides are named 'anhydride' replacing the word 'acid' in parent carboxylic acid, like (CH3CO)2 (CH3CO)2O is known as acetic anhydride.
  • Although slower reacting than acid chlorides, anhydrides react with water to form carboxylic acids, with alcohols to form esters, and with amines to form amides. Anhydrides can also be reduced to 1o alcohols by hydride reduction.25 sept. 2022
