Out of benzene, m–dinitrobenzene and toluene which will undergo nitration most easily and why?

Description : Out of benzene, m–dinitrobenzene and toluene which will undergo nitration most easily and why?

Last Answer : Ans. -CH3 group is electron donating while –NO2 group is electron withdrawing. Therefore, maximum electron density will be in toluene , followed by benzene and at least in m-dinitrobenzene. Therefore, the ease of nitration decreases in the order: Toluene> benzene> m-dinitrobenzene

Although — NH2 gp is an ortho and para directing gp, nitration of aniline gives along with ortho and para, meta derivatives also.

Description : Although — NH2 gp is an ortho and para directing gp, nitration of aniline gives along with ortho and para, meta derivatives also.

Last Answer : Nitration is carried out with a mixture of Conc. NO3 + Conc. H2 SO4 (nitrating mix). In the presence of these acids, most of aniline gets protonated to form anilinium ion. Therefore, in the ... is m-directing and deactivating hence a mixture of all three-ortho, para and meta derivatives is formed.
