Question

which functional group is found in an amine?

Explanation:

An amine is an organic compound with a nitrogen - containing functional group. The general structure of an amine has a nitrogen atom bonded to hydrogen atoms and alkyl or aryl groups. The functional group of an amine is -NH₂ (primary amine), -NHR (secondary amine), or -NR₂ (tertiary amine), which is represented by the structure $\text{R}-\text{N}-\text{H}$ with hydrogen atoms attached to the nitrogen. The first structure is an ester functional group ($\text{R}-\text{C}(=\text{O})-\text{O}-\text{R}$), and the third structure is a carbonyl group ($\text{R}-\text{C}(=\text{O})-\text{R}'$).

Answer:

The second option with the $\text{R}-\text{N}-\text{H}$ structure.
