KCET 2019 | Compounds Containing Nitrogen Question 19 | Chemistry

If aniline is treated with $$1: 1$$ mixture of conc. $$\mathrm{HNO}_3$$ and conc. $$\mathrm{H}_2 \mathrm{SO}_4$$, p-nitroaniline and $$m$$-nitroaniline are formed nearly in equal amounts. This is due to

$$m$$-directing property of $$-\mathrm{NH}_2$$ group

protonation of $$-\mathrm{NH}_2$$ which causes deactivation of benzene ring

$$m$$ and $$p$$ directing property of $$-\mathrm{NH}_2$$ group

isomerisation of some $$p$$-nitroaniline into $$m$$-nitroaniline
