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 .

Example: Ethanal with molecular formula

2. Amines have functional group .

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

3. Ketones have functional group .

Example: Acetone with molecular formula

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

fire could start, buildings collapsing, and ash falling from the sky.

explanation:
