Before reacting aniline with HNO_(3) for nitration, it is converted to acetanilide. Why is this done and how is nitroaniline obtained subsequently ? |
|
Answer» <P> Solution :It is because aniline gets oxidised and protonated and GIVES 47% m-nitroaniline on direct NITRATION. THEREFORE, it is converted into acetanilide and then nitrated. ANILIDE group activates the ring at o- and p- positions. We get o- and p- nitroacetanilide which on hydrolysis gives o- and p- nitroaniline. |
