and benzoicacidssubstituted in the meta- and para-positions with trimethylammonium [-N(CH_3)_3^⊕] groups. The experimental results offer no support for preferential relay of the inductive effect of a substituent group to the ortho- and para-positions of a benzene ring as postulated by Robinson, Ingold and others. The strong meta-orienting influence of the -N(CH_3)_3^⊕ in electrophilicaromatic substitution
