Chemistry Question on Chemical Reaction

Reaction of aniline with conc. HNO3 and conc. H2SO4 at 298 K will produce 47% of:\text{Reaction of aniline with conc. HNO}_3 \text{ and conc. H}_2\text{SO}_4 \text{ at 298 K will produce 47\% of:}

A

p-Nitroaniline

B

o-Nitroaniline

C

m-Nitroaniline

D

2,4-Dinitroaniline

Answer

p-Nitroaniline

Explanation

Solution

The reaction of aniline with a mixture of concentrated nitric acid (HNO3_3) and sulfuric acid (H2_2SO4_4) leads to nitration. Under these conditions, nitration occurs primarily at the ortho and para positions relative to the amino group. The given conditions (298 K) result in the major product being 47% of para-nitroaniline.
