For indexing purposes, it may be convenient to designate a functional modification of a characteristic group described in a name by a prefix, such as "oxo-", by a functional class name, such as
oxime; such a name for this example would be 1-methyl-4-oxocyclohexa-2,5-diene-1-carboxylic acid 4-oxime.
