WebbAmines are a family of chemical compounds that share as a common feature the presence of at least one nitrogen atom whose hybridisation depends on the structure of the molecule. For example, aliphatic amines contain sp 3 -hybridised nitrogen atoms. This hybridisation lies between sp 3 and sp 2 when the amine is part of a resonance structure.
