Concept explainers
Interpretation:
Among the given options, the correct pairing of prefix and the numbering system used for locating substituents has to be chosen.
Concept Introduction:
Benzene derivatives are compounds that contain benzene as the core with substituents in the benzene ring. This is done by replacement of one or more hydrogen atoms with other atoms in the ring. Substituents like alkyl groups or halogen groups are generally found. IUPAC name for monosubstituted benzene derivative use the name of the substituents as prefix to the name benzene.
If two substituents are present in the benzene ring, then it is known as disubstituted benzene derivative. Three isomers are possible for disubstituted benzene. The three isomers can be given as,
If the substitution is in first and second position, then it is known as ortho substitution. If the substitution is in first and third position, then it is known as meta substitution. If the substitution is in first and fourth position, then it is known as para substitution.
