The partition coefficient, abbreviated P, is defined as a specific ratio of the concentrations of a solute between the two solvents (a biphase of liquid phases), and the ratio's logarithm is thus log P. The log P value is a gauge of lipophilicity or hydrophobicity when one of the solvents is water and the other is a non-polar solvent. The lipophilic and hydrophilic phase types must always be in the numerator and denominator, respectively, according to the established precedence. What is the log P of this molecule?
