Abstract: The Electrical conductivity of N-(2-ChloroBenzylidene)-4-picolylamine was benchmarked in different solvents including water & methanol at temperature range of (293-313K) at 5K intervals, and in (Methanol-Water) mixture at 298K in different percentage (10%, 20%, 30%, 40% and 50%). Then plotting the relation between equivalent conductivity (?) and square root of molar conc. (?Conc.). By using Kohlrausch equation the plot shows that the Schiff base compound act as weak electrolyte, i.e., weak association in water, methanol and (Methanol-Water) mixture. Then applying (Lee-Wheaton) equation for symmetrical electrolyte (1:1) to calculate different thermodynamic parameters including: Association constant (KA), equivalent conductivity at infinite dilution (??), main distance between ions (R), and Standard deviation (??). The values of (?H, ?H, ?S) were measured utilizing (Van’t-Hoff) equation. The final step including theoretical calculations to optimize the molecular energy of the compound and measuring different parameters in gas phase, water and methanol using (AM1, PM3) and DFT/B3LYP/6-31G.
