	FAQ
		Organic compounds, depending on their properties, are able to partition between the two liquid phases and into the gas phase.
		First, if the organic compounds 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.

	Organic compound - Wikipedia, the free encyclopedia
		An organic compound is any member of a large class of chemical compounds whose molecules contain carbon, with the exception of carbides, carbonates, carbon oxides and elementary carbon.
		The study of organic compounds 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 organic compounds.
		The theory that organic compounds were fundamentally different than those that were "inorganic", that is, not synthesized through a life-force, was disproven with the synthesis of urea, an organic compound, from potassium cyanate and ammonium sulfate by Friedrich Wöhler.

	Organometallic compound - Wikipedia, the free encyclopedia
		An organometallic compound is partially characterized by the presence of one or more metal-carbon bonds, in which the carbon involved would, apart from the metal-carbon bond, be otherwise considered a part of an organic compound.
		Some organometallic compounds derived from electropositive elements, such as Grignard reagents and organolithiums, have a high electron density on the carbon.
		In certain organometallic compounds such as ferrocene or dibenzenechromium, the pi-orbitals of the organic moiety ligate the metal.

		An organic compound is any of a large class of chemical compounds whose molecules contain carbon, with exception of carbides, carbonates and carbon oxides.
		Organic compounds are studied in organic chemistry; many of them, such as proteins, fats and carbohydrates, are also of prime importance in biochemistry.

		Because many organic compounds have relatively low boiling points and/or dissolve easily in organic solvents there exist many methods for separating mixtures into pure constituents that are specific to organic chemistry such as distillation, crystallization and chromatography techniques.

	Representing Organic Compounds: Structural Formulas.
		Because of the complexity of the structure of many organic compounds, as well as the importance of structure in organic chemistry, the development of shorthand methods for representing the structures of organic compounds has been almost mandatory in order to allow the drawing of structures in a reasonable amount of space and time.
		It is still, however, possible to simplify the representation of an organic compound even further without compromising its ability to convey useful information about the structure and bonding of the compound.
		Practically all of the chemistry of organic compounds occurs at functional groups because the electrons in the carbon-carbon and carbon-hydrogen single bonds of the carbon skeleton are seldom directly involved in reactions - they are tightly held between the two nuclei, and they are seldom accessible to external reagents or respond to their influences.
