In nitration reactions, the position of the nitro group depends on the activating and deactivating effects of substituents already on the aromatic ring.
Step 1: Understanding the reaction.
Acetanilide reacts with concentrated nitric acid in the presence of concentrated sulfuric acid to undergo nitration at the para position. The product formed is P - nitroaniline.
Step 2: Analyzing the options. (A) P - nitroaniline: This is the correct product of the nitration of acetanilide at the para position. (B) O - nitroacetanilide: This is not the product; the nitration occurs at the para position of the aromatic ring. (C) Aniline: This is not the product; it is formed from acetanilide under different conditions. (D) Nitrobenzene: Nitrobenzene is not formed in this reaction.
Step 3: Conclusion.
The correct answer is (A) P - nitroaniline, as it is the product of nitration at the para position.
