To convert aniline into p-Nitroaniline, three steps are taken. Arrange following given steps in correct sequence.
A. N-Phenyl ethanamide is treated with HNO3, H2SO4 and heated at 288 K.
B. p-Nitro acetanilide undergoes acidic or basic hydrolysis to give p-Nitroaniline.
C. Aniline is treated with acetic anhydride in pyridine.
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
By protecting the –NH2 group by acetylation reaction with acetic anhydride, the nitration reaction can be controlled, and the p-nitro derivative can be obtained as the major product.
Three steps:
Step 1: C. Aniline is treated with acetic anhydride in pyridine.
Step 2: A. N-Phenyl ethanamide is treated with HNO3, H2SO4 and heated at 288 K.
Step 3: B. p-Nitro acetanilide undergoes acidic or basic hydrolysis to give p-Nitroaniline.
