Vedclass · Answer

(B) In the presence of concentrated $H_2SO_4$,aniline $(Ph-NH_2)$ undergoes protonation to form the anilinium ion $(Ph-NH_3^+)$.The reaction is: $Ph-NH_2 + H^+ \rightarrow Ph-NH_3^+$.The $-NH_3^+$ group is strongly electron-withdrawing and meta-directing due to its positive charge.Therefore,during nitration,the major product formed is $m$-nitroaniline,resulting in a high percentage of the meta product compared to other substituted benzenes where the substituents are ortho/para-directing.

Nitration of which of the following reactants gives the maximum $\%$ of the meta product (using $HNO_3 / H_2SO_4$)?
