3) Assign partition constants to substances

This table provides logarithmic partition constants log K iem> air/octanol

with K i air/octanol = C i air /C i octanol ) of the substances i = 2-Hexanone, n-Hexane, 1-Heptanol, 1-Hexanol, between air and the solvent octanol.

Substance i

Log K i air/octanol

i = ?

-2.1

i = ?

-3.8

i = ?

-5.3

i = ?

-5.8

Assign the partition constants to the substances and explain shortly what made you choose this particular substance.
