==Key Stage 4==
===Meaning===
The [[Alkene Test]] is a technique to identify whether a [[hydrocarbon]] contains two [[Carbon]] [[atom]]s with a [[Double Bond|double bond]] to one another.
===About the Alkene Test===
: The '''alkene test''' identifies [[Unsaturated Hydrocarbon|unsaturated hydrocarbons]].
: The '''alkane test''' is 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 [[Dibromoalkane]].
: [[Ethene]] + [[Bromine]] → [[Dibromoethane]]
: <chem>C2H4 + Br2 -> C2H4Br2</chem>
