Study Notes
Classification of Amines
- CH3CH2NH2 is a primary amine.
- Ethylmethylamine is classified as a secondary amine, not tertiary.
Types of Amines
- A tertiary amine features three alkyl or aromatic groups bonded to a nitrogen atom.
- Primary amines have the highest boiling points and are most soluble in water among amine types.
Hydrogen Bonds
- Hydrogen bonds in amines are weaker than those found in alcohols.
Ionization and Reactions
- Ionization of propylamine in water can be represented as:
CH3CH2CH2NH2 + H2O ⇌ CH3CH2CH2NH3+ + OH−. - Amides are formed when a carboxylic acid reacts with an amine.
- Acid hydrolysis is the reaction that reverses amidation, resulting in a carboxylic acid and an ammonium salt.
Chemical Behavior in Water
- Dissolving ethylamine in water results in the formation of ethylammonium hydroxide.
- Substituted, tertiary, secondary, aromatic, and primary amines are capable of forming hydrogen bonds.
Boiling Points Comparison
- Butylamine has a higher boiling point than diethylamine.
- Propylamine has a higher boiling point compared to butane.
Amino Acids
- Essential amino acids are those that cannot be synthesized by the body and must be acquired through diet.
- The structural formulas of amino acids differ primarily in their side (R) groups.
- All α-amino acids contain a carboxylate group and an ammonium group.
- Basic amino acids possess an R group that contains an amine group.
