Ethylene is a small hydrocarbon, the colourless flammable gas which is denoted by a formula C 2 H 4 or H 2 C=CH 2.Ethene is the IUPAC name for ethylene. Ethylene oxide vapor may be initiated into explosive decomposition in absence of air [Hess, L. G., et al., Ind. The Journal of Physical Chemistry B 2006 , 110 (25) , 12372-12379. Boiling point is very high due to intermolecular hydrogen bonding. For more specific values, follow the links immediately below. Ethylene (C 2 H 4) is a colorless and sweet-smelling gas.It occurs naturally in plant tissue, but for industrial purposes, it is obtained by thermal cracking of naphtha or low alkanes.
