Hydrogen bonding between substitute 1-Octanol 1-Decanol, and acetophenone, o-bromo acetophenone in carbontetra chloride system. The molecular interaction of the complex, molar polarization (pab), and dipole moment (Dm) were calculated. Discussed above this method Huyskens based on the Onsager theory in all the system exploration of dipole moment of the complexes are reported. (c) 2021 Elsevier Ltd. All rights reserved.
