dc.description.abstractThe ultrasonic velocities (U), densities (ρ), and viscosities (η) were measured for solutions containing equimolar concentrations of eight aldehydes namely, benzaldehyde, o-chlorobenzaldehyde, anisaldehyde, p-tolualdehyde, cinnamaldehyde, crotonaldehyde, propionaldehyde, and valeraldehyde as acceptors, benzylamine and cyclohexylamine as donors in n-hexane at 303K. Acoustical parameters such as adiabatic compressibility (β), free length (Lf), viscous relaxation time (ґ), molecular interaction parameter (χu) have been computed. These values indicate the formation of charge transfer complexes between aldehydes and amines. Formation constant (K) values of the complexes have been evaluated using a modified Bhat equation proposed by Kannappan. The constant values of free energy of activation (ΔG#) and relaxation time indicate the formation of similar type of complexes in these systems. However, the variation in free energy of formation (ΔG) values suggests that their thermodynamic stability depends on the structure of donor and acceptor.en_US
