Abstract	On the baisis of the calculations by the two centre Huckel method for sigma electron system, the electronic structure of the various aliphatic amines including ammonia, and the relationship between the observed pKb and the change in the sigma electronic energy, ΔEσin the course of protonation are discussed. A parallelism is observed between the pKb and the calculated ΔEσ of the amines. Also, it is observed that the electron densities of hydrogen atom directly bonded to nitrogen of the amines, likewise have a linear relationship with the pKb. Therefore, the basicity of the aliphatic amines may be estimated qualitatively by means of the two center Huckel method.
