This is a Short Type Questions as classified in NCERT Exemplar
Ans: As −NH2 is a strong activating group, the aniline will readily undergo electrophilic substitution reaction, and it is difficult to cease reaction at the mono substitution stage.
Therefore, the activating group −NH2 is protected by an acetylation process.
The acetylated complex formed utilizes the lone pair of nitrogen and are less available for donation, this helps to carry out the nitration reaction easily.
