Intermediate IUPAC Nomenclature VII Benzenes When a single substituent is present on a benzene it is a monosubstituted benzene. o Monosubstituted benzenes are with the base name benzene and using the substituent group as a prefix. o The substituent is always at C-1 so there is no need to number its location. Examples of monosubstituted benzenes: Cl NO 2 chlorobenzene propylbenzene nitrobenzene tert -butylbenzene or (1,1-dimethylethyl)benzene Many monosubstituted benzenes have common names, some of these names have been included in IUPAC nomenclature as base names for the structure. Common names of monosubstituted benzenes: common name (full IUPAC name) CH 3 OH OCH 3 NH 2 O H O OH O Cl O OCH 3 O NH 2 toluene (methylbenzene) phenol (benzenol) anisole (methoxybenzene) aniline (benzenamine) styrene (ethenylbenzene) benzaldehyde (benzenecarbaldehyde) benzoic acid (benzenecarboxylic acid) benzoyl chloride (benzenecarbonyl chloride) methyl benzoate (methyl benzenecarboxylate) benzamide (benzenecarbamide) CN benzonitrile (benzenecarbonitrile) O CH 3 acetophenone (1-phenyl-1-ethanone) Common names in bold face are considered to be IUPAC correct base names for structures.
