A. Structures and Reactions of Amines

Amines whose structures are derived from ammonia can be categorized as primary amines, secondary amines or primary amines. Since amines have a non-bonding pair of electrons on the nitrogen atom, they generally react as bases. Some biologically relevant amines include noradrenaline and adrenaline. Now that you’re familiar with the reactions and structures of amines, see if you can identify them in the activity below.

1. Identify the amine from the compounds given below.

2. Categorize each of the following amines as either a primary amine, secondary amine or tertiary amine.

3. The reaction below is an example of an acid-base reaction. Identify the acid, the base, the conjugate acid and the conjugate base in the reaction.

4. Noradrenaline is a primary amine while adrenaline is a secondary amine. Identify noradrenaline and adrenaline from the structures given below.

B. Naming Primary Amines

Primary amines can be named by writing the name of the alkyl substituent followed by “amine” as the suffix.

For example;

CH3 CH2 CH2 NH2

is propylamine because the alkyl group has three carbon atoms.

Provide the names of each of the following primary amines:
