The geometries, heat of formations (ǻHf), entropies (ǻS),  proton affinities (PA), atomic charges (q), nucleophilicities (n), substituted constants (ı) and local electrophilic sensitivities (s), were calculated for some alkylated pyridine derivatives after full geometry optimization using AM1, PM3 and PM5  methods in both aqueous and gas phases for studied molecules. The calculated acidity constants, pKa values, were evaluated by means of searching the possible correlation between experimentally obtained results and the computed data.
