WebApr 14, 2015 · Simple aromatic alcohols with other substitutions (e.g. 4-chlorophenol) can thus be named as substituted phenols. Third, "benzyl" and "benzene" similarly sound the same but should be treated as distinct concepts. Substituted aromatic rings can be named as benzene derivatives, such as chlorobenzene. Usually, a "phenyl group" is synonymous with C6H5− and is represented by the symbol Ph or, archaically, Φ. Benzene is sometimes denoted as PhH. Phenyl groups are generally attached to other atoms or groups. For example, triphenylmethane (Ph3CH) has three phenyl groups attached to the same carbon center. Many or even most phenyl compounds are not described with the term "phenyl". For example, the chloro derivative C6H5Cl is normally called chlorobenzene, although it … fanatic\\u0027s 4bWebIpso-substitution describes two substituents sharing the same ring position in an intermediate compound in an electrophilic aromatic substitution.
