The dipolemoment have been determined by using the mixtures of aniline, o-chloro aniline , p-chloro aniline and 2methoxy ethanol at 30 0 C based on the Onsager theory and Huysken's method. The dipolar increments of the systems were computed from the bond angle data available from molecular orbital theory. The enhancement of the dipole moment values confirms the hydrogen bonding between all the systems.
