Using data at C from Table 1; values from refs. [9, 10]; values from refs.[5, 6]; the 70-0% MeOH, 80-10% Acetone, 100TFE, 70TFE(w/w), 50TFE(w/w) values are from reference [23]; is the number of solvents. With associated standard error. Accompanied by standard error of the estimate. Correlation coefficient. F-test value. All solvents. Probability that the contribution to the linear free energy relationship is insignificant. Excluding 100EtOH. In exactly the same solvents as 2.
