Carboxylic acid reacts with ammonia to form ammonium salts which on heating produces
- A. Carbonates
- B. Alkane
- C. Ester
- D. Amide
Explanation
The ammonium carboxylate loses a molecule of water on strong heating and the nitrogen ends up bonded directly to the carbonyl carbon, giving an amide. An ester would require an alcohol rather than ammonia, which is the standard confusion here. The amide link formed in this way is the same one that joins amino acids in a protein.
