What Turns Bromine Water Colourless, This is a positive test for an unsaturated compound. It has a brownish-red color with a bleach-like odor, and it dissolves in water. When bromine water is added to an unsaturated compound, the former gets The bromine water test is a widely used qualitative test in organic chemistry for detecting unsaturation and reactive aromatic compounds in organic Alkenes react rapidly with bromine at room temperature to form colourless dibromoalkanes. For ketones When a ketone reacts with bromine water, Watch as orange bromine water is added to an alkene. Bromine water is often used as a regent to prove the presence of carbon-carbon double bonds in compounds. Cycloocta-1,3,5,7-tetraene has the molecular formula C 8 H 8. Pentene (CH3CH2CH=CHCH3) reacts with bromine by undergoing an addition Bromine water is a dilute solution of bromine that is normally orange-brown in colour, but becomes colourless when shaken with an alkene. If the Bromine Water turns from orange to colourless, then an unsaturated hydrocarbon, such as an alkene is present. 1.
