→About Alkenes
: [[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]]
: C<sub>2</sub>H<sub>4</submath> C_2H_4 + Br<sub>2</sub> Br_2 → C<sub>2</sub>H<sub>4</sub>Br<sub>2C_2H_4Br_2</submath>
