1. Amines
AH Chemistry, Unit 3(b)

2. Overview Organic derivatives of ammonia
One or more of the hydrogen atoms replaced with an alkyl or aryl group
Can be classified as primary, secondary or tertiary

3. Physical properties Does hydrogen bonding exist in amines?
Primary and secondary only
How does this affect their solubility?

4. Naming Two methods for primary amines:
Remove the “e” from the parent hydrocarbon and add the suffix “-amine”
e.g. ethanamine
Add the suffix “-amine” to the name of the substituent group
e.g. ethylamine

5. Secondary and tertiary amines are named by citing the substituent group, R, preceded by the prefix “di” or “tri” respectively, followed (without a space) by “amine”
e.g. dimethylamine, butyldimethylamine
* If the amine group is not the principal group in the compound, it is named “amino”

6. Ethylamine
2-propylamine
Triethylamine

7. Chemical properties Amines are weak bases
Why?
React with aqueous mineral acids and carboxylic acids
Producing salts
