WebApr 23, 2024 · alkynes do not decolourise bromine water. alkynes have one or more triple bonds between them. when reacted with bromine water, the bromine breaks its bonds with water and forms bonds with the akynes, so the alkyne can replace the triple bod with a double bond. How does bromine water test for alkenes? 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 ...
