Explanation

Acetamide, which is a primary amide and has the chemical formula CH3CONH2, is typically prepared by heating ammonium acetate.

Here's the reaction:

CH3COO −NH4+ → CH3CONH2 + H2O

In this reaction, ammonium acetate (CH3COONH4) decomposes upon heating to form acetamide (CH3CONH2) and water (H2O).

This process is a type of thermal decomposition reaction.
