WebMar 22, 2024 · What happens when bromine reacts? Reactions: Bromine. Bromine reacts with water to produce hypobromite, OBr-. The pH of the solution determines the … WebBromine in CCl4 is red. When bromine reacts with an alkene or an alkyne, the alkyl halide formed is colorless; hence the disappearance of the red color is a positive test for unsaturation. A student tested the contents of two vials, A and B, both containing compounds with the molecular formula C6H12. Vial A decolorized bromine, but vial B … WebAlkynes also react with bromine liquid and give alkyl halides as products. But difference is alkyne can reacts with two bromine molecules while alkene is limited to one bromine molecule if these is only one double bond in the alkene. So four bromine atoms will be added to the ethyne molecule when excess bromine liquid is added. sixth sense vaughan
