- AminesAmines are organic compounds derived from ammonia, NH3, in which one or more hydrogen atoms have been replaced by carbon-containing groups (alkyl or…
- Naming AminesSimple amines are named by adding -amine to the name of the alkyl group attached to the nitrogen. • CH3NH2 is methylamine; CH3CH2NH2 is ethylamine…
- Amines as BasesAmines, like ammonia, are Brønsted-Lowry bases: they are proton acceptors.
- Relative Base Strength of AminesAmmonia, primary aliphatic amines and primary aromatic amines are all bases, but they differ in strength.
- Preparing Primary Aliphatic AminesPrimary aliphatic amines can be made by reacting a halogenoalkane with ammonia.
- Reduction of NitrilesNitriles contain the C≡N group.
- Preparing Aromatic AminesAromatic amines are made by reducing aromatic nitro compounds.
- Amines as NucleophilesA nucleophile is an electron pair donor.
- Quaternary Ammonium SaltsA quaternary ammonium ion is a positive ion in which a nitrogen atom is bonded to four alkyl (or aryl) groups, R4N+.
- Cationic SurfactantsA surfactant (surface active agent) is a molecule with a water-loving (hydrophilic) part and a water-hating (hydrophobic) part, so it collects at…
