Molecular interactions have been studied from the formation of H-bonded complex between P- Chloroacetophenone in carbon tetra chloride with alcohol such as Butanol, Iso-butanol, P-Cresol. The first two are the aliphatic alcohols whereas the remaining one is aromatic alcohol. The dipole moment of 1:1complexes of the above said alcohols with P-Chloroacetophenone in carbon tetra chloride are computed by experimentally measured quantities like that density , refractive index and dielectric constants using Huysken’ s model based on Onsager's theory. Dipolar increment has been calculated for all the studied systems from the bond angle available from molecular orbital studies. This investigation shows that in all the studied systems of dipole moments of the complexes are reported and the observed enhancement of dipole moment of the complexes are discussed.
