Inorganic compounds are produced by non-living naturalprocesses or by human intervention in the laboratory. This was the most common definition of "organic" until Wohler's 1828 synthesis of urea (an organic compound) from ammonium cyanate (a salt, and therefore? Organic/inorganic). But we no longer use this definition, for the simple reason that many compounds that everyone agrees are organic -- including "natural products" which are routinely made by living things -- have been synthesized by humans.  Organic compounds contain carbon-hydrogen bonds. Inorganic compounds don't.
