Basicaly, TCE is an ethylene molecule composed of two Carbon (C) atoms and four Hydrogen (H) atoms. The molecules composed only of hydrogen and carbon are called hydrocarbons (petrol). With a few exceptions, the composites witch contain carbon are called organic composites . Thus, ethylene is an hydrocarbon molecule and an organic molecule.
