The Basicity Of Amines |
-Lone pair of electrons on nitrogen atom can form a dative bond with a H+ ion -Donates electrons and "accepts" proton |
|
|
|
Amine are Neutralised by acids Form Amine Salts |
CH₃NH₂ + HCl→ CH₃NH₃+Cl- Methylamine +Hydrochloric Acid 2CH₃CH₂NH₂ + H₂SO₄→ (CH₃CH₂NH₃+)₂SO₄²⁻ Ethylamine +Sulphuric Acid |

Preparation of a Amine
|
-Heat Halogenoalkane with excess ammonia and ethanol solvent (Forms NH₄Br⁻) 1 -Excess of ammonia prevents hydrogen from further substituting to form 2° and 3° amines Without excess of ammonia HBr formed
