what happens when benzamide is heated with dilute mineral acid
Answers
Hydrolysis of aromatic amide gives carboxylic acids. When benzamide is heated with dilute mineral acid, benzoic acid is obtained.
When benzamide is heated with dilute mineral acid we get benzoic acid and a salt ammonium chloride as products.
Dilute mineral acid is hydrochloric acid and when amide is heated with acid t is an example of hydrolysis reaction of aromatic amines under acidic conditions.
The acid act as catalyst for reaction between amide and water thus increasing rate of reaction. As a mineral acid is used generally hydrochloric acid so along with formation of corresponding acid an inorganic salt is also formed.
So on reaction of bezamide with hydrochloric acid which is mineral acid we get benzoic acid and ammonium chloride as an inorganic salt.
The reaction is:---
C6H5CONH2 + H2O + HCl---------->C6H5COOH + NH4Cl .
