Question

Amino group is ortho-para directir,but nitration of aniline gice a substantial amount of m-nitoaniline.Give rrason

Answer 1

Answer:

sorry I can't understand the question

Answer 2

$\huge\textcolor{indigo}{\rm{Answer :-}}$

Reason :-

Under strongly acidic conditions of nitration (in the presence of a mixture of conc. $HNO_3 + H_2SO_4$), aniline gets protonated and is converted into anilinium ion having —$NH_3^+$ group.

This group is deactivating group and m-directing. So, the nitration on aniline gives o, p-nitroaniline (mainly p-product) while the nitration of aniline ion gives m-nitroaniline.

Thus, nitration of aniline gives a substantial amount of m-nitroaniline due to protonation of aniline.
