Final answer:
The term used to describe derivatives of benzene with two substituents is disubstituted benzene.
Step-by-step explanation:
The term used to describe derivatives of benzene with two substituents is disubstituted benzene.
An alternate system for naming disubstituted benzene rings uses three different prefixes: ortho, meta, and para.
For example, in 1,2-dimethylbenzene, the two methyl groups are in the ortho position, meaning they are on adjacent carbon atoms.
