Boiling Points of Amines |
The order of boiling points of amines is: Primary > Secondary > Tertiary Intermolecular hydrogen bonding is more in primary amines than in secondary amines. Tertiary amines do not have intermolecular hydrogen bonding due to the absence of a hydrogen atom |
|
Basicity of Amines |
The order of basicity in the gaseous phase is: Tertiary amine > secondary amine > primary amine > NH3 The order of basicity in aqueous solution is: (C2H5)2NH > (C2H5)3N > C2H5NH2 > NH3 (CH3)2NH > CH3NH2 > (CH3)3N > NH3 |
|
Arylamines |
The basicity of aniline or aromatic amines is less than that of ammonia because aniline is more stable than anilinium ion Electron releasing groups increase basic strength, e.g. OCH3, –CH3, whereas electron-withdrawing groups like –NO2, –SO3H, –COOH, –X decrease it |
|
Benzoylation |
Amines react with benzoyl chloride (C6H5COCl) CH3NH2 + C6H5COCl → CH3NHCOC6H5 + HCl |
|
Carbylamine Reaction |
|
|
Benzenediazonium Chloride |
|
|
Hinsberg’s Reagent |
Benzenesulphonyl chloride (C6H5SO2Cl) It reacts with primary and secondary amines to form sulphonamides Tertiary amines do not react with benzenesulphonyl chloride |
