Dipole moment studies of H-bonded complexes of phenols and substituted phenols with benzaldehyde in tetrachloromethane

Abstract

The dipole moment of 1:1 hydrogen bonded complexes of phenols and substituted phenols with benzaldehyde were determined from dielectric measurements at a temperature of 308.16 K. The dipole moment of the complex (<img src='/image/spc_char/micro.gif' border=0>_ab), molar polarisation (<i style="">P</i>_ab), interaction dipole moment (<img src='/image/spc_char/delta.gif' border=0><img src='/image/spc_char/micro.gif' border=0>) for all the ternary systems were calculated for most favourable consideration predicted thermodynamically. The results indicate that complexation is predominantly due to polarization as well as electrostatic interaction.
