Answer:
Explanation:
One test for Alkenes is testing with bromine water. This test can be used to tell the difference between an Alkanes and Alkenes. On a normal, any Alkene will turn brown bromine water to colourless because the bromine reacts with the double carbon-carbon bond. Also, the reaction takes place with unsaturated compounds that contains the double carbon-carbon bonds.
Conversely, when Alkanes go through the same test, there is no reaction with bromine water.
