Summary, etc. Volumetric and acoustic properties of p-cymene with fluorobenzene, chlorobenzene and bromobenzene have been investigated using density, (<em>ρ</em>), and speed of sound, (<em>U</em>) measurements over the entire composition range at T= (303.15, 308.15 and 313.15) K. From the experimentally measured density, (<em>ρ</em>); Excess molar volumes, (<em>V</em><img src="http://nopr.niscair.res.in/jinfo/em1.gif" border="0" alt="" />), infinite dilution partial molar volume, (<em><img src="http://nopr.niscair.res.in/jinfo/vbar.gif" border="0" alt="" /><img src="http://www.niscair.res.in/jinfo/subscript8.gif" border="0" alt="" />, i</em>) excess partial molar volume, (<img src="http://nopr.niscair.res.in/jinfo/vbar.gif" border="0" alt="" /><img src="http://www.niscair.res.in/jinfo/subscript8.gif" border="0" alt="" />,<img src="http://nopr.niscair.res.in/jinfo/ei.gif" border="0" alt="" />) apparent molar volume, (<em>V,<sub>m,ϕ, 1</sub></em>), infinite dilution apparent molar volume, (<em>V</em>, <img src="http://www.niscair.res.in/jinfo/subscript8.gif" border="0" alt="" />, <sub>ϕ, 1</sub>) with empirical parameters, <em>S<sub>v</sub></em>, <em>B<sub>v</sub></em> and limiting apparent molar expansibility, (<em>E</em><img src="http://nopr.niscair.res.in/jinfo/zerophi.gif" border="0" alt="" />) have been calculated. Deviation in speed of sound (<img src="http://www.niscair.res.in/jinfo/delta.gif" border="0" alt="" /><em>U</em>), deviation in isentropic compressibility, (<img src="http://www.niscair.res.in/jinfo/delta.gif" border="0" alt="" />k<sub>s</sub>), deviation in acoustic impedance, (<img src="http://www.niscair.res.in/jinfo/delta.gif" border="0" alt="" /><em>z</em>), infinite dilution partial molar isentropic compressibility, (<img src="http://nopr.niscair.res.in/jinfo/kbar.gif" border="0" alt="" /><img src="http://www.niscair.res.in/jinfo/equation144.gif" border="0" alt="" />,<sub>m, i</sub>), excess partial molar isentropic compressibility, (<img src="http://nopr.niscair.res.in/jinfo/kbar.gif" border="0" alt="" /><img src="http://www.niscair.res.in/jinfo/equation144.gif" border="0" alt="" /><img src="http://nopr.niscair.res.in/jinfo/em1.gif" border="0" alt="" />,<sub>i</sub>), apparent molar isentropic compressibility, (<em>K<sub>s,m,ϕ,i</sub></em>), infinite dilution apparent molar isentropic compressibility, (<em>K<img src="http://www.niscair.res.in/jinfo/equation144.gif" border="0" alt="" /><sub>m,ϕ,1</sub></em>) with empirical parameters <em>S<sub>k</sub></em> and <em>B<sub>k</sub></em> and intermolecular free length (L<sub><em>f</em></sub>) have been calculated using experimentally measured speed of sound, (<em>U</em>). To derive fitting coefficients, (<em>Ai</em>) with standard deviation, (σ), excess properties were fitted to the Redlich-Kister type polynomial equation. Various theoretical speed of sound and average deviations have been calculated using well established equation like Nomoto, (<em>U<sub>nmt</sub></em>) Ideal Mixing Rule, (<em>U<sub>imr</sub></em>) Junji, (<em>U<sub>junji</sub></em>) and Jacobson’s Free Length Theory, (<em>U<sub>flt</sub></em>). The variation of these properties with composition and temperature has been discussed in terms of molecular interaction on mixing and their interacting abilities have also been compared.
