Study Notes
Amines Classification
- CH3CH2NHCH3 is a secondary amine.
- CH3CH2NH2 is a primary amine.
- (CH3CH2)2NH is classified as an amine.
- Dimethylamine is designated as CH3-NH-CH3.
Names and Structures of Amines
- N-methyl-3-bromoaniline is derived from HNCH3-benzene ring-Br.
- Aminobenzene is formally referred to as aniline.
- Ethyldimethylamine is represented as CH3-NCH2CH3-CH3.
Properties and Functional Groups
- Amines are nitrogen-containing compounds capable of forming hydrogen bonds.
- Tertiary amines, like (CH3CH2)3N, do not form hydrogen bonds.
- Primary amines contain one carbon-containing group bonded to nitrogen, while secondary amines have two.
- The characteristic functional group in alkaloids is an amine.
Reaction and Hydrolysis
- Ethylamine in water creates ethylammonium hydroxide.
- Diethylamine reacts with HCl to yield diethylammonium chloride.
- The hydrolysis of amides can produce corresponding acids and amines when treated with acids or bases.
Biological Significance of Amines
- Amines can act as Bronsted-Lowry bases.
- Quaternary ammonium compounds like choline have a positive nitrogen charge.
- Histamine, an active amine, is associated with allergic reactions.
Medicinal Chemistry
- Amine salts are commonly used in drug formulations due to their increased solubility.
- Alkaloids, including nicotine, quinine, and morphine, are biologically active nitrogen compounds.
- Local anesthetics such as Procaine and Lidocaine are derived from modifications of cocaine.
Miscellaneous
- Heterocyclic compounds are cyclic structures containing nitrogen.
- Amides are derivatives of amines and carboxylic acids, and are involved in various chemical reactions.
- Acid and base hydrolysis of amides produces corresponding acids and amines or ammonium salts.
Boiling Points and Solubility
- Amines generally have higher boiling points than similar hydrocarbons due to hydrogen bonding.
- Water solubility of amines decreases with an increasing number of carbon atoms; typically, amines with fewer than six carbon atoms are soluble.
True/False Statements
- Aniline is confirmed as a primary aromatic amine.
- Ethylmethylamine is not a tertiary amine, hence that statement is false.
- Amine salts and heterocyclic amines like pyrrolidine possess physiological significance and are correctly identified.
Summary of Reactions
- Amidation between acetic acid and ammonia yields acetamide.
- The reaction between benzoic acid and ethylamine produces N-ethylbenzamide, showcasing the amide functionality.
- Hydrolysis reactions allow amides to revert to their respective acids and amines under the right conditions.
