Amines constitute an important class of organic compounds derived by replacing one or more hydrogen atoms of NH 3 molecule by alkyl / aryl group( s).
In the IUPAC system, the amines are regarded as alkanamines, e. g.,
Structure
The nitrogen atom in amine is spa-hybridised. The three hybrid orbitals are involved in bond formation and one hybrid atomic orbital contains the lone pair of electrons, giving the pyramidal geometry of amines.
