AMINES
Amines can be considered as derivatives of ammonia,
obtained by replacement of one, two or all the three
hydrogen atoms by alkyl and/or aryl groups For example:
Like ammonia, nitrogen atom of amines is trivalent and
carries an unshared pair of electrons Nitrogen orbitals
in amines are therefore, sp3 hybridised and the geometry
of amines is pyramidal Each of  the three sp3 hybridised
orbitals of nitrogen overlap with orbitals of hydrogen or
carbon depending upon the composition of the amines
