The acoustical properties of chlorosubstituted pyrazoles have been investigated from the ultrasonic velocity and density measurements at different concentration and different percentages in dioxane-water mixture at 3050 k. The adiabatic compressibility (βs), acoustic impedence (Z), inter molecular free length (Lf), apparent molal volume (ÑÃ?â??Ã?â??v) and relative association (RA) values have been calculated from the experimental data of velocity and density measurement at concentration range 0.01-0.000625 mol/lit and 70%, 75%, 80% dioxane-water mixture. These above parameters are used to discuss the structural and molecular interactions.
