WebReaction with Bromine. Unsaturated hydrocarbons react rapidly with bromine in a solution of carbon tetrachloride or cyclohexane. The reaction is the addition of the elements of … WebIn an addition reaction to an alkene two covalent C-Br bonds are formed, and the color of the bromine fades as the colorless product is generated. In a substitution reaction of a hydrocarbon a C-Br covalent bond is also formed, but this product is accompanied by release of of an equal molar quantity of hydrogen bromide gas.

"WebThe substitution reactions occur through radical intermediates. During the initiation step of the reaction, the bond between two bromine atoms is broken homolytically. When this happens two bromine radicals form. In a propagation step, those bromine radicals can react with a hydrocarbon forming HBr and a hydrocarbon radical.

WebAug 13, 2024 · (Hexane, the saturated hydrocarbon with six carbon atoms has the formula C 6 H 14 —eight more hydrogen atoms than benzene.) However, despite the seeming low level of saturation, benzene is rather unreactive. It does not, for example, react readily with bromine, which, is a test for unsaturation.
