Dielectric study of Allyl chloride (AC) , Alcohol and their binary mixtures have been carried out over the frequency range from 10 MHz to 10 GHz at temperature 288 K using Time Domain Reflectometry (TDR) for 11 different concentrations. Dielectric constant, Relaxation time, Kirkwood correlation factor, Excess parameters were estimated and discussed to yield information on the molecular structure and dynamics of the mixture. The values of dielectric constant and relaxation time decreases with increase in concentration of alcohol in Allyl chloride. The Bruggeman plot shows a non-linearity of the curve for all the concentration; indicates the hetrointeraction which may be due to hydrogen bonding of the OH group of alcohol with Allyl chloride molecule. The excess inverse relaxation time values are negative for all the concentrations indicate that the solute-solvent interaction hinders the rotation of the dipoles of the system.
