To better reflect its structure, acetic acid is often written as CH 3 −C(O)OH, CH 3 −C(=O)−OH, CH 3 COOH, and CH 3 CO 2 H. In the context of acid–base reactions, the abbreviation HAc is sometimes used, [12] where Ac in this case is a symbol for acetate (rather than acetyl).

When necessary, the position of the hydroxyl group is indicated by a number between the alkane name and the -ol: propan-1-ol for CH 3 CH 2 CH 2 OH, propan-2-ol for CH 3 CH(OH)CH 3. If a higher priority group is present (such as an aldehyde, ketone, or carboxylic acid), then the prefix hydroxy-is used, [19] e.g., as in 1-hydroxy-2-propanone (CH ...
In solution, it can ionize by a loss of a proton to produce the lactate ion CH 3 CH(OH)CO − 2. Compared to acetic acid, its pK a is 1 unit less, meaning lactic acid is ten times more acidic than acetic acid. This higher acidity is the consequence of the intramolecular hydrogen bonding between the α-hydroxyl and the carboxylate group.
acetic acid (CH 3 COOH) → acetyl chloride (CH 3 COCl) benzoic acid (C 6 H 5 COOH) → benzoyl chloride (C 6 H 5 COCl) butyric acid (C 3 H 7 COOH) → butyryl chloride (C3H7COCl) (Idiosyncratically, for some trivial names, -oyl chloride substitutes -ic acid. For example, pivalic acid becomes pivaloyl chloride and acrylic acid becomes acryloyl ...
