Account for the following:
(i) Aniline is acetylated to prepare its monobromo derivative.
(ii) Before nitration, aniline is converted into aceanilide.
or Before reacting aniline with `HNO_(3)` for nitration, it is converted into acetanilide. why is it done and how is nitroaniline obtained subsequently?

Why is NH_(2) group of aniline acetylated before carrying our nitration

(a) Account for the following : (i) Direct nitration of aniline yields significant amount of meta derivative. (ii) Primary aromatic cannot be prepared by Gabriel phthalimide synthesis. (b) Carry out the following conversions : (i) Ethanoic acid into methanamine. (ii) Aniline to p-Bromoniline. (c) Arrange the following in increasing order of basic strength : Aniline, p-nitroaniline and p-toludine.
