WebThe bromine water test is used to assess if an alkene or alkyne does have an unsaturated carbon-carbon bond. The test employs an addition reaction, in which a reactant, in this case, bromine, is introduced to an organic molecule in a way to destroy a double or triple bond. Bromine has an orange-brownish hue in the solution. WebThe general formula for alkene is CnH2n. Alkenes are insoluble in water but are soluble in orgainic solvent. The presence of double bond between carbon-carbon atoms is a strong link. However, the second pi bond which is not as strong as the first sigma bond is more vulnerable to attack by suitable reagent, causing alkene to become relatively ...
