Why do we write some chemical names in a different manner (for example the name of ascetic acid)?

Chemical names are written in different manner as per different theories, but the standard procedure is rules by IUPAC.
Acetic acid can be represented in both ways. Both notations are correct but the notation that has the group 'COOH' is used to make it obvious that you are dealing with an acid. All organic acids have this grouping - an Oxygen atom double-bonded to Carbon and a Hydroxy group bonded to the same carbon. The Hydrogen atom in this group is readily available for acid chemistry.
