WebOCH3 group is more electron withdrawing (i.e, shows more -I effect) than the OH group. WHY? The reason is that, there are two lone pairs of oxygen. Oxygen has a smaller size, so in case of OCH 3, the methyl group is close to the lone pair electrons, which leads to … WebThe presence of the -OCH 3 group at the meta position cannot exert its +R effect on the -NH 3 group, but it can exert its -I effect due to the presence of electronegative oxygen. Hence m-anisidine is a weaker base than aniline and it is found to be even weaker than o-anisidine.
