Question

Nitration of aniline also gives m- nitroaniline along with o- nitro and p- nitroaniline, in strong acidic medium because (A) In electrophilic substitution reaction amino group is meta directive (B) Strong acid, gives nitrate anion, which attacks at m- position (C) In strong acidic medium aniline present as anilinium ion (D) In strong acidic medium, nitration of aniline is a nucleophic substitution reaction

<img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/c-isoo7nujjdnv.png" /> The reason for this is that, in acidic condition protonation of -NH2 group gives anilinium ion - overset⊕ textN textH text3 , which is of deactivating nature and of m-directive nature.

Q. Nitration of aniline also gives $m -$ nitroaniline along with $o -$ nitro and $p -$ nitroaniline, in strong acidic medium because

In electrophilic substitution reaction amino group is meta directive

Strong acid, gives nitrate anion, which attacks at $m -$ position

In strong acidic medium aniline present as anilinium ion

In strong acidic medium, nitration of aniline is a nucleophic substitution reaction

The reason for this is that, in acidic condition protonation of $- N H_{2}$ group gives anilinium ion $- N \oplus H_{3}$ , which is of deactivating nature and of m-directive nature.

Q. Nitration of aniline also gives m− nitroaniline along with o− nitro and p− nitroaniline, in strong acidic medium because
