![]() In this form, the positions of the hydrogen atoms are not fixed the molecules may rotate freely around the long axis. On cooling under normal pressure, the first modification to appear is a plastic crystal, crystallizing in the cubic system. ![]() Solid ethane exists in several modifications. Properties Īt standard temperature and pressure, ethane is a colorless, odorless gas. Ethane was discovered dissolved in Pennsylvanian light crude oil by Edmund Ronalds in 1864. This error was corrected in 1864 by Carl Schorlemmer, who showed that the product of all these reactions was in fact ethane. They mistook the product of these reactions for the methyl radical ( CH 3), of which ethane ( C 2H 6) is a dimer. ĭuring the period 1847–1849, in an effort to vindicate the radical theory of organic chemistry, Hermann Kolbe and Edward Frankland produced ethane by the reductions of propionitrile ( ethyl cyanide) and ethyl iodide with potassium metal, and, as did Faraday, by the electrolysis of aqueous acetates. He mistook the hydrocarbon product of this reaction for methane and did not investigate it further. Ethane was first synthesised in 1834 by Michael Faraday, applying electrolysis of a potassium acetate solution.
