Abstract
Molecular interactions of tetrabutylammonium salts prevailing in organic solvent media have been analyzed, both qualitatively and quantitatively, using conductometric studies and validating the results with Fourier transform infrared (FT-IR) measurements. From conductometric studies of tetrabutylammonium tetrafluoroborate [Bu4NBF4] and tetrabutylammonium perchlorate [Bu4NClO4] in nitromethane (NM), N-methyl formamide (NMF), and formamide (FA) at 298.15 K, it is revealed that high molecular interaction is mainly because of ion–dipole interactions, which is evidenced from the FT-IR measurements. The 1978 Fuoss conductance-concentration equation in terms of the limiting molar conductance (Λo), the association constant (KA), and the association diameter (R) was used to interpret the conductance data. Tetrabutylammonium tetraphenylborate [Bu4NBPh4] as the “reference electrolyte” was used to estimate the ionic contributions to the limiting molar conductance. The degree of interaction is articulated in terms of ...
