Nomenclature of Monosubstituted Benzenes
- Monosubstituted benzenes are named by adding the substituent as a prefix to the parent compound benzene.
Classification of Benzene and Similar Compounds
- Benzene and substances with similar structures and chemical properties are classified as arenes.
Diamylbenzenes
- Dimethylbenzenes are also known as xylenes.
Nitration of Benzene
- The compound formed when benzene undergoes nitration is nitrobenzene.
Halogenation of Benzene
- The product of the halogenation of benzene with bromine is bromobenzene.
Phenyl Group
- The C6H5- group is known as the phenyl group.
Alkylation of Benzene
- The product of the alkylation of benzene with chloroethane is ethylbenzene.
- In alkylation of benzene, the net addition is replacement of a hydrogen atom by an alkyl group.
