Addition is a reaction in which the molecules of two or more substances unite without the formation of a by-product.

The addition of unsaturated ethene and bromine molecules results in a colorless substance. During the reaction the Pi bond in the ethane molecules is broken, as soon as the double bond is opened, a bromine molecule attaches to each carbon atom. This reaction can take place at room temperature.
