Steric Parameters of Hydroxamic Acids in DMSO

Piyush Thakur, Sandhya Patre, and Rama Pande

Abstract—Steric parameters, such as apparent molar volumes, molar volume, molar refraction and excess properties of two hydroxamic acids, N-o-tolyl-4-methylbenzo- and N-ptolyl- 2-methylbenzo- have been calculated from experimental data of densities (ρ), refractive index (n) in dimethyl sulfoxide at various temperatures (298.15 to 318.15 K). Results obtained have been discussed in terms of intermolecular interactions and a comprehensive discussion has been provided. The apparent molar volumes at infinite dilution and the slopes of Masson’s equation are computed to interpret the solute-solvent interactions. The expansibility is also calculated. Structure breaking capacities of these molecules is inferred from the sign of [∂V 0 f /∂T] P, Both the compounds behave as structure breakers in DMSO.

Index Terms—Apparent molar volume, Density, Expansibility and hydroxamic acid, Refractive index.
