Relative viscosities of Me4NBr, Et4NBr, Pr4NBr and Bu4NBr in 10% (W/W) 2-( Ethoxy ) ethanol - water mixture are measured at 30o, 35o and 40oC. The data has been analyzed on the basis of Jones-Dole equation. The viscosity B-coefficients, and their temperature coefficients show that Et4NBr, Pr4NBr and Bu4NBr are structure makers in the present solvent system contrast to Me4NBr a structure breaker. The B-Coefficients are divided into their ionic components. B-values of R4N+ ions are divided into BEinst and BReinf values. Solute - solvent interaction parameters (Δ) are calculated to understand the structural effect of solute. Applying transition state theory quasi-thermodynamic parameters are also calculated. Positive solvation numbers for Et4NBr, Pr4NBr and Bu4NBr indicate structure making property of these ions. The dimensions of the R4N+ ions are also calculated.
