Question

Fig. 3.4 shows that when plotting the air-pure liquid compound partition constants of a large number of chemicals versus their dispersive vdW parameters, the apolar and monopolar compounds fall more or less on one line, while the bipolar compounds do not show this behavior. Explain these findings. For which kind of bulk liquids (give examples) would you expect that in a similar plot, all com pounds (including the bipolar ones) should fit one line?

Answer 1

Bipolar compound have different properties from mono polar and apolar compounds their chemistry is different so they are not lie on the given line.
