The dividing line between organic and inorganic is somewhat controversial and historically arbitrary, but generally speaking, organic compounds have carbon-hydrogen bonds, and inorganic compounds do not. Thus carbonic acid is inorganic, whereas formic acid, the first fatty acid, is organic, although it could as well be called "carbonous acid" and its anhydride, carbon monoxide, is inorganic.
The name "organic" is a historical name, dating back to 19th century, when it was believed that organic compounds could only be synthesised in living organisms through vis vitalis - the "force of life".
Most pure organic compounds are artificially produced. Ironically the term "organic" is also used to describe products produced without artificial chemicals. See organic production.
Organiccompounds, depending on their properties, are able to partition between the two liquid phases and into the gas phase.
First, if the organiccompounds that you want are in the public library (these are the ones that are always present in the drop-down box on the Available Compounds page) then first follow the instructions given in answer to question 2 in the section above.
The volatility of the compound expressed as a vapour pressure or Henry's law constant, its solubility in water with respect to the solid compound or hydrate, dissociation constants (if the compound is an acid), and how its activity coefficients in the liquid phase(s) are calculated.
The study of organiccompounds is termed organic chemistry, and what with it being such a vast collection of chemicals (over half of all known chemical compounds), systems have been devised to classify organiccompounds.
The theory that organiccompounds were fundamentally different than those that were "inorganic", that is, not synthesized through a life-force, was disproven with the synthesis of urea, an organiccompound, from potassium cyanate and ammonium sulfate by Friedrich Wöhler.
