An additivity model of the apolar solute‐solvent parameter log(L16) was verified using sets of 939 nonaromatic and 1075 aromatic compounds. Unbiased distributions of errors and of the contribution significance level were statistically tested. An an

An additivity principle was formulated for functional and atom groups and their structural and interactional contributions to the log L16 criterion, expressing apolar solute-solvent interactions in gas-liquid chromatography. Numerical values were cal
