Amide Formation (Acetic Acid + Ammonia)
CH3COOH + NH3 → CH3CONH2 + H2O
Overview
Acetic acid reacts with ammonia to first form ammonium acetate, which upon strong heating loses water to form acetamide. The amide bond (C-N) is the same linkage found in proteins (peptide bonds). Direct thermal dehydration is energy-intensive; industrial methods use acyl chlorides or coupling reagents.

Everyday Example
Every protein in your body is held together by amide (peptide) bonds, the same type of bond formed in this reaction.
Industrial Importance
Amide bond formation is fundamental to peptide synthesis, pharmaceutical manufacturing, and nylon production (polyamide).
