1. A disubstituted benzene is named using the prefix ortho- (o), meta- (m) or para- (p).
2. Identify the substituents and their positions with respect to one another and assign them priority.
For example in the second compound, the substituent -nitro is written as the prefix and the substituent -COOH is written as the suffix of the compound.
