How can you separate the products ortho and para in the nitration of acetanilide?
Ortho nitro acetanilide is separated from para nitro acetanilide by dissolving the solution in ethanol. o-nitroacetanilide is more soluble in ethanol as compared to water.
How do you get para nitroaniline?
Nitronium ion is the electrophile generates from fuming nitric acid in presence of fuming sulphuric acid. In the second step p-nitroaniline is prepared from p-nitro acetanilide due to hydrolysis of acetate ion from acetamido functional group in presence of concentrated sulphuric acid.
Why glacial acetic acid is used in nitration of acetanilide?
Glacial acetic acid is used because it is a polar solvent capable of dissolving acetanilide and the acetate ion is a poor nucleophile, so no substitution is possible.
What is the formula of Acetanilide?
C8H9NO
Acetanilide/Formula
Which reagent is required nitration of acetanilide?
Acetanilide also exhibits reagent-dependent orientation in nitration; nitric and sulfuric acids yield paranitroacetanilide as major product, while with nitric acid – acetic anhydride, ortho- nitration is favored (10).
Why do we get para substituted product for nitration of acetanilide?
The electrophile -NO2 will attach the para position because the -NHCOCH3 is an electron releasing group. In order to protect the amino group from oxidation acetanilide is first nitrated to give p-nitroacetanilide and then on hydrolysis to give p-nitroaniline which is difficult to obtain by direct nitration.
How do you convert aniline to para nitroaniline?
Nitration: Direct nitration of aniline yields (p-nitroaniline) a mixture of ortho, meta, and para nitroanilines. In an acidic medium the -NH2 group is protonated to the -N+H3 group which is meta-directing and deactivating. Hence, a considerable amount of m-nitroaniline is obtained.
How do you prepare 4 nitroaniline as the major product from aniline?
p-nitroaniline : Acetanilide on treatment with nitric acid in the presence of sulphuric acid gives p-nitroacetanilide which on acidic hydrolysis gives p-nitroaniline as major product.

What happens when Acetanilide is treated with nitrating mixture?
When acetanilide is treated with nitrating mixture that is a mixture of nitric acid and sulphuric acid p-nitroacetanilide is formed. Along with p-nitroacetanilide, o-nitroacetanilide is also formed as a minor product. Since o-nitroacetanilide is very much soluble in alcohol it is very easy to isolate p-nitroacetanilide through crystallization.
How to prepare P-nitroacetanilide from acetic acid and acetic acid?
To prepare p-Nitroacetanilide from acetanilide and acetic acid in the presence of nitrating mixture. The organic compound p-nitroacetanilide is prepared from acetanilide through nitration. When acetanilide is treated with nitrating mixture that is a mixture of nitric acid and sulphuric acid p-nitroacetanilide is formed.
What is the chemical name of 4-nitro acetanilide?
Para-Nitroacetanilide is also known as 4-nitro acetanilide. This is a chemical compound that is a Nitroacetanilide derivative prepared from acetanilide and nitrating mixture along with a trace amount of ortho product is also formed. This organic compound is prepared from acetanilide.
What is the composition of para nitroacetanilide?
Para nitroacetanilide is also called 4-Nitroacetanilide, para nitroacetanilide is a chemical compound that is a nitroacetanilide derivative prepared from acetanilide and nitrating mixture. Along with para product a trace of ortho product is also formed.
