It is remarkable that the position of the halogen in the molecule has no effect on the heat of formation; for example, chlorpropylene and allylchloride, and also ethylene dichloride and ethylidene dichloride, have equal heats of formation.
A consequence of this empirical division was that marsh gas, ethylene and cyanogen were regarded as inorganic, and at a later date many other hydrocarbons of undoubtedly organic nature had to be included in the same division.
In general, therefore, it may be considered that the double linkages are not of exactly the same nature as the double linkage present in ethylene and ethylenoid compounds, but that they are analogous to the potential valencies of benzene.

It can be obtained synthetically by reducing ethylene cyanide by the action of sodium in absolute alcohol.
Dichloride of ethylene is detected by shaking up the chloroform with dry potassic carbonate, and then adding metallic potassium.
Technically, ethylene is a fairly difficult gas to produce in large quantities, but, for the Ludwigshafen works, these difficulties were a thing of the past.

This group contains a benzene and also an ethylene group, being derived from styrolene C6H5.
By following the change on the model, it is seen that in the resulting figure the two chlorine atoms in ethylene chloride are situated at angles of the two tetrahedrons which are nearest each other.
If the two carbon atoms unite by the ethylenekind of union, the union will be along a line corresponding to one of the edges of each tetrahedron.
Long, difficult, and expensive operations were required to produce this result, for the extreme degree of cold it demanded had to be produced by boiling large quantities of ethylene in a vacuum.
Causing liquid ethylene to boil in an air-pump vacuum at -103° C.
One of a series of artificial, organic bases, usually produced as thick viscous liquids by the action of ammonia on ethylene oxide.
Ethylene decomposes somewhat easily under the influence of the electric spark, or a high temperature.
It will be enough to point out the fact that sulphuric acid does not absorb ethylene under ordinary conditions of contact, but only after continued shaking, by which means the number of points of contact is greatly increased.
Ethylene is colourless, has a slight ethereal smell, is slightly soluble in water, and somewhat more soluble in alcohol and in ether (in five volumes of spirit and six volumes of ether).
Two volumes of marsh gas give only two volumes of carbonic anhydride, and two volumes of ethylene give four volumes of carbonic anhydride.
It is remarked that the explosion of mixtures of oxygen with marsh gas, ethylene and cyanogen is transmitted more quickly if the oxygen be taken in such a proportion that the carbon should burn to oxide of carbon, i.

This intrinsic luminosity of ethylene remains almost constant when the latter is diluted with carbonic oxide, until the ethylene forms only 40 per cent.
That when the proportion of ethylene in such mixtures is above 63 per cent.
In the case of mixtures of ethylene and marsh-gas, the intrinsic luminosity of the former is augmented with increasing rapidity as the proportion of marsh gas rises, the intrinsic luminosity of ethylene, in a mixture containing 10 per cent.
When the ethyleneis diluted with hydrogen, its intrinsic luminosity rises to 81 candles when the ethylene constitutes 30 per cent.
