Nomenclature of Monosubstituted Benzenes
Benzenes with a single substituent are named by adding the substituent's prefix to the word benzene.
Disubstituted Benzenes
In disubstituted benzenes, the position of the substituents is indicated with the prefixes ortho (position 1,2), meta (position 1,3), and para (position 1,4).
Nomenclature of Benzenes with Multiple Substituents
Derivatives with three or more substituents are named by numbering the ring in such a way that the substituted carbons receive the lowest possible locators.
