WebbHydrocarbons are classified as saturated, actively unsaturated, aromatic or an arene based on various classification tests involving test for solubility in concentrated H2SO4, ignition, active unsaturation using Baeyer’s test and Bromine test, aromaticity using nitration test, and basic oxidation test. WebbDuring a Bromine test, the presence of bromine will combine with the carbon-carbon double bond of alkenes and create dibromo alkanes. After this reaction occurs the bromine molecule is consumed which will produce the dark-red brown color. A positive test will be seen if there is a quick disappearance of bromines color.
