Edexcel IAL Chemistry A2 19.3 amine solubility and basicity
For solubility draw the hydrogen bond to water; for basicity compare how available the nitrogen lone pair is after alkyl donation or delocalisation into a ring.
How this is tested
- Draw hydrogen bonding between amines and water with lone pairs and dipoles.
- Compare basicity of aliphatic amines, ammonia and phenylamine using lone-pair availability.
- Explain phenylamine or caffeine weakness by nitrogen lone-pair delocalisation.
