: [[Alkene Test|Testing for '''alkenes''']] can be done by adding them to [[Bromine Water]]. If the [[Bromine Water]] turns from orange to colourless, then an [[alkene]] is present. During this test the [[Bromine]] [[Chemical Reaction|react]]s with the [[alkene]] to form a [[Bromoalkane]].

: [[Ethene]] + [[Bromine]] → [[Dibromoethane]]
