Magritek. (, August 21). An Introduction to the Synthesis of p Author: Magritek. Dec 16, · The --NH2 group is electron donating, and the --NO2 group is electron withdrawing it may help to think of it as the --NH2 is "pushing" electron density into the ring, and the nitro is "pulling" electron density out of the ring.
In industry, o-nitroaniline and p-nitroaniline are obtained by heating the corresponding nitrochlorobenzenes with ammonia; m-nitroaniline is produced by partial reduction of m-dinitroben-zene with sodium sulfide.
Nitroanilines are blood poisons, and the combined action of nitroanilines and ethyl alcohol is particularly dangerous. Why does ortho nitro aniline form only 2% on performing nitration of aniline.
Nitration of Aniline in Conc. H 2 SO 4 and HNO 3, we can understand the formation of both para and meta nitro aniline.
