Abstract
The mean square dipole moments of the 1:1 complexes of tri-n-butyl phosphate (TBP) with 1-hexanol, 1-heptanol and 1-octanol in benzene are determined following two different methods i.e., one based on Onsager's method and the other using modified Palit's method. The interaction dipole moment for the thermodynamically most favoured geometry of 1:1 complexes of the system involving 1-hexanol, 1-heptanol, 1-octanol as the first components and TBP as the second component is evaluated. The results indicate that complexation is predominantly due to polarization effect involving charge redistribution. Furthermore, the induced excess polarization and apparent complexation constant in these mixtures are calculated.
