| Abstract: | This work presents a grouping scheme of some pure solvents (which are able to form hydrogen-bonded complexes) and their binary mixtures on the basis of the similarity of their molecular-microscopic properties. The solvatochromic parameters ~ *, f and g developed by Kamlet, Abbound and Taft, are selected as clustering variables. The Ward's Method and the Group Average Method are applied as clustering procedures. The study pays particular attention to the microscopic solvent feature common to all solvents included in each cluster, describing the relevant solvating properties. It also contributes to a better understanding of the similarities and differences of the explored solvents. In addition, the correspondence between reaction rates and solvent chemical properties is evaluated through the application of linear solvation energy relationships. |
