Webb12 jan. 2024 · p-Nitroacetanilide is prepared by nitration of acetanilide. The acetamide organization (-NHCOCH 3) in acetanilide is the ortho and para directing. Thus, in nitration, the sum of o- and p-nitroacetanilide is shaped. As the acetamido organization is a huge group, it poses a steric challenge to the ortho function.
WebbThere are no good, general ways to prepare an aniline (ArNH 2) directly from the parent aromatic (Ar-H) by EAS or related methods, so usually aromatic amines are made by nitration followed by reduction.
