- Bromine_test abstract "In organic chemistry, the bromine test is a qualitative test for the presence of unsaturation (carbon to carbon double or triple bonds) and phenols.An unknown sample is treated with a small amount of elemental bromine — either as an aqueous solution, or as a solution in dichloromethane or carbon tetrachloride. Unsaturation and/or phenol is shown by the disappearance of the deep brown coloration of bromine when the bromine has been used up by reaction with the unknown sample. The formation of a white precipitate (a brominated phenol) indicates that the unknown was a phenol. The more unsaturated an unknown is, the more bromine it can decolourise.It has more affinity towards carbon with less alpha hydrogens and has a The presence of unsaturation can also be determined using Baeyer's reagent. The iodine value is a way to determine the presence of unsaturation quantitatively.The bromine test is a simple qualitative test. Modern spectroscopic methods (e.g. NMR and infrared spectroscopy) are better at determining the structural features and identity of unknown compounds.".
