Answer: ammonia

Explanation:- Functional groups are specific group of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules.

1. Aldydes have functional group [tex]-O=C-H[/tex].

Example: Ethanal with molecular formula [tex]CH_3CHO[/tex]

2. Amines have functional group [tex]-NH_2[/tex].

Example: Methylamine with molecular formula [tex]CH_3NH_2[/tex]. they are formed by substituting one hydrogen of ammonia by a R substituent.

3. Ketones have functional group [tex]-C=O[/tex].

Example: Acetone with molecular formula [tex]CH_3COCH_3[/tex]

4. Nitric acid is a inorganic acid with molecular formula [tex]HNO_3[/tex].
