Question

Amines are derivatives of the ______ molecule.

aldehyde
ammonia
acetone
nitric acid

Answer 1

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
`-O=C-H`.

Example: Ethanal with molecular formula
`CH_3CHO`

2. Amines have functional group
`-NH_2`.

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

3. Ketones have functional group
`-C=O`.

Example: Acetone with molecular formula
`CH_3COCH_3`

4. Nitric acid is a inorganic acid with molecular formula
`HNO_3`.

Answer 2

Amines are derivatives of the ammonia molecule. Ammonia or azane is a compound of nitrogen and hydrogen, it is a colorless gas with a characteristic pungent smell.
