Abstract: For the present study, the estimation of the static dielectric constants, dielectric constant at an angular frequency and dielectric loss of methyl, ethyl and propyl amines with 2-fluorobenzoic acid in 1,4-dioxane were carried using Klystron microwave bench at frequency 9.43GHz. Using the dielectric parameters, the overall relaxation time and group rotation relaxation time of the polar solute molecules and average relaxation times  were also determined using Higasi and Gopalakrishna method employing Debye’s equations. The obtained results revealed that, out of five different molar ratios, relaxation time  is maximum at 1:1 molar concentration for all the systems due to inter and intramolecular interactions through hydrogen bonding. In addition, the dipole moment, activation viscous flow and dielectric relaxation due to molar free energy also been discussed.
