Interpretation:

Each of the disubstituted benzene is to be named.

Concept introduction:

In disubstituted benzenes, two hydrogen atoms have been substituted by the halogen atoms like bromine, fluorine iodine or by the group of carbon atoms like methyl, ethyl, propyl, etc.

During the naming of disubstituted benzenes, substituents are numbered and listed alphabetically.

The order of numbering within the ring of disubstituted benzenes is done by the alphabetical order of the substituents.

If the two substituents are identical, the prefix di- is used.
