important ingredient of illuminating gas, and also obtained

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}.

hydrocarbons of which ethylene is the type, and
represented by the general formula {CnH2n}.
