Solution

## Structural Isomers of disubstituted benzene:Structural Isomers are the compounds in which the compounds have the same molecular formula but different structural formulas.In structural isomerism, the arrangement of atoms or groups of atoms is different.Benzene is a six-membered aromatic compound.In Benzene, the first or original substituted group is numbered as one, and the remaining substituted group is numbered as two.If groups are substituted on the $1-2$ position, then it is known as the ‘Ortho’ substitution or ‘Ortho’ isomer.If the substitution is at $1-3$ the position, then it is called a ‘Meta’ substitution or isomer.Disubstituted benzene in which position of groups are $1-4$ is known as ‘Para’ substitution or isomer.Hence, there are three isomers that are possible for disubstituted benzene.
