It is an unsaturated compound and combines directly with chlorine and bromine to form oily liquids (Dutch liquid), -- hence called olefiant gas. Called also ethene, elayl, and formerly, bicarbureted hydrogen.
Ethylene series (Chem.), the series of unsaturated hydrocarbons of which ethylene is the type, and represented by the general formula CnH2n.

Ethylene ( IUPAC name: ethene) is a hydrocarbon which has the formula or HC=CH. It is a colorless flammable gas with a faint "sweet and musky" odor when pure. It is the simplest alkene (a hydrocarbon with carbon-carbon double bonds), and the second simplest unsaturated hydrocarbon after acetylene .
Ethylene is widely used in the chemical industry, and its worldwide production (over 150 million tonnes in 2016 ) exceeds that of any other organic compound. Much of this production goes toward polyethylene, a widely used plastic containing polymer chains of ethylene units in various chain lengths. Ethylene is also an important natural plant hormone, used in agriculture to force the ripening of fruits. Ethylene's hydrate is ethyl alcohol.
