Thus, (CH 3 CO) 2 O is called acetic anhydride. Mixed (or unsymmetrical) acid anhydrides, such as acetic formic anhydride (see below), are known. One or both acyl groups of an acid anhydride may also be derived from another type of organic acid, such as sulfonic acid or a phosphonic acid.ixed (or unsymmetrical) acid anhydrides, such as acetic formic anhydride (see below), are known.

Viewing Notes: 1  HCOOH is called Methanoic Acid or Formic Acid. 2  When you see COOH in a Lewis structure it is called a carboxylic acid functional group (see video for Lewis structure).3  The carboxylic acid functional group is commonly seen in organic and biochemistry courses. 4  HCOOH is the simpliest structure containing a carboxylic acid functional ... The carboxylic acid functional group is commonly seen in organic and biochemistry courses. 2  HCOOH is the simpliest structure containing a carboxylic acid functional group. 3  There are a total of 18 valence electrons for the HCOOH Lewis structure.
