Structure of the following compounds-

In p-toluidine, the methyl group increases the electron density at the N atom (+I effect of methyl), so it is more basic than aniline. In p-nitroaniline, the nitro group is an electron withdrawing group, so it decreases the electron density from N atom, so it is less basic than aniline.
