General Equation to Express Changes in the Physicochemical Properties of Organic Homologues.

ABSTRACT: Changes in various physicochemical properties (P _(n)) of organic compounds with the number of carbon atoms (n) can be roughly divided into linear and nonlinear changes. To date, there has been no general equation to express nonlinear changes in the properties of organic homologues. This study proposes a general equation expressing nonlinear changes in the physicochemical properties of organic homologues, including boiling point, viscosity, ionization potential, and vapor pressure, named the "NPOH equation", as follows: P _(n) = P ₍₁₎ α ^n - 1 e ^{∑_i=2 n(β/(i - 1))} where α and β are adjustable parameters, and P ₍₁₎ represents the pr
