Question

Acidic hydrolysis of acetamide gives:
A. Acetaldehyde
B. Acetic acid
C. Methylamine
D. Formic acid

Answer 1

Hint: The general name of the compound ethanamide is acetamide. It is chemically represented as\[{\rm{C}}{{\rm{H}}_{\rm{3}}}{\rm{CON}}{{\rm{H}}_{\rm{2}}}\] . It is prepared from ethanoic acid. In laboratory preparation, it is prepared from ammonium acetate via the process of dehydration. It smells like ammonia or vinegar.

Complete Step by Step Solution:
Let’s first understand what a hydrolysis reaction is. The reaction in which the reaction of a chemical compound with water takes place is termed hydrolysis reaction. If the hydrolysis reaction takes place in the acidic medium, then the hydrolysis reaction is termed acidic hydrolysis.

Now, we will understand the acidic hydrolysis of acetamide. In the hydrolysis reaction of acetamide, the Carbon-Nitrogen bond gets broken. And the nucleophilic attack of the hydroxyl ion at the carbocation takes place. This results in getting the product of carboxylic acid. The deprotonated hydrogen forms a bond with \[{\rm{N}}{{\rm{H}}_{\rm{2}}}\] and forms ammonia. The acidic hydrolysis of the acetamide is,

\[{\rm{C}}{{\rm{H}}_{\rm{3}}}{\rm{CON}}{{\rm{H}}_{\rm{2}}} + {{\rm{H}}_{\rm{2}}}{\rm{O}} \overset{H^{+}}{\rightarrow} {\rm{C}}{{\rm{H}}_{\rm{3}}}{\rm{COOH}} + {\rm{N}}{{\rm{H}}_{\rm{3}}}\]

Therefore, the acetamide on acidic hydrolysis gives acetamide and ammonia.
Hence, option B is right.

Note: There is easy solubility of acetamide in water, benzene, and chloroform. It belongs to the class of amides that is obtained from the condensation of acetic acid with ammonia. In nature, it is found in beetroot. Some of the uses of acetamides are explosive making, stabiliser, hygroscopic agent, etc. It is a substance of combustible nature. The heating of acetamide produces toxic gases. Exposure to Acetamide is dangerous to health.
