Reactions of Aromatic Compounds - Page 1 Chapter 14 Reactions of Aromatic Compounds Nomenclature of Benzene Derivatives Some monosubstituted benzenes are named as derivatives of benzene. Examples: Cl Br NO2 CH2CH3 Chlorobenzene Bromobenzene Nitrobenzene Ethylbenzene Others have trivial names which must be learned: NH2 CH3 OH CH CH 2 Aniline Toluene Phenol Styrene With two substituents, isomers are possible: Cl Cl Cl Cl Cl Cl 1,2-dichlorobenzene o-dichlorobenzene 1,3-dichlorobenzene m-dichlorobenzene 1,4-dichlorobenzene p-dichlorobenzene CH3 CH3 CH3 CH3 CH3 CH3 o-xylene m-xylene p-xylene Reactions of Aromatic Compounds - Page 2 CH3 NO2 OH CH3 CH3 Br o-nitrotoluene m-hydroxytoluene p-bromotoluene OH Cl Br Br NH2 O2N If there are three or more groups, use numbering system.
