Answer: The correct answer is : 2) Ammonia
Amine :
These are organic compound which are derivatives of ammonia (NH₃) gas . In Amine one or more Hydrogen atom in ammonia are replaced by carbon atom.
The general structure of ammonia as bond between N and carbon . Number of carbons may vary from 1 to 4 .(Image attached )
Example : CH₃-NH₂ , CH₃-NH-CH₃
2) Amides :
These are organic compound in which the Hydroxyl (OH) group of carboxylic acid (COOH) is replaced by amino group (NH₂) . SO they are derivatives of carboxylic group but since they also have amino group , so they can be said as derivatives of ammonia . (image attached )
Example : CH₃-CO-NH2 , CH₃-CO-NH-CH₃ .
Hence it can be said that Amine and Amide are derivaties of ammonia (NH₃)
