Abstract: The quantitative structure-property relationships (QSPR) model for pKa values of 43 organic compounds in acetonitrile were established by using electrotopological state indices as descriptors. Leave-one-out cross validation was performed, which confirmed the good stability and powerful prediction of this model. A satisfactory relationship is expressed as
