Correlation of stability constants of hydrocarbon complexes with silver nitrate in ethylene glycol

Abstract

A correlation method suggested by a micropartition (MP) model of solution is applied to published g.l.c.-derived data for the stoicheiometric stability constants of a range of C₄–C₆ unsaturated hydrocarbons with Ag⁺ in solution in ethylene glycol. The correlation is successful for 11 families of compounds, although the grouping within families is unexpected. On the basis of this correlation it is shown that true stability constants are almost certainly greater than the values customarily cited for Ag⁺–unsaturated compound pairs and a route to quantitative evaluation of ‘solvent effects’ is indicated.
