The solution will remain coloured. With cyclohexene the bromine adds across the double bond and the solution will become colourless. The predominant product is trans-1,2 dibromocycolhexane as the bromine atoms add from opposite side of the ring. …
WebFeb 28, 2024 · Halogenation of alkanes is a radical process, that tends to be indiscriminate (i.e. dihalogenated products are possible in that radical mechanisms can be quite unselective): H3CCH2CH3 +Br2 hν −→ H3CCHBrCH3 +HBr. The mechanism of halogenation is in your text, and the starting point is the homolysis of the bromine molecule by UV light: … WebAug 5, 2016 · 1 Answer Sorted by: 1 The iron and bromine must first react to form the catalyst (FeBr3) as the iron does not actually catalyze the reaction (this is known as in situ synthesis of the catalyst). The FeBr3 catalyzes the reaction between toluene and Br2 to form ortho and para bromotoluene.
WebBromine is dark red liquid and upon reacting with a double bond, turns colorless. Mixed halogenations can also be achieved. For example, a mixture of Br 2 and Cl 2 have been used to perform bromochlorination. The reaction is possible because the halogen bond is relatively weak and polarizable. WebJan 23, 2024 · The double bond breaks, and a bromine atom becomes attached to each carbon. The bromine loses its original red-brown color to give a colorless liquid. In the case of the reaction with ethene, 1,2-dibromoethane is formed. This decoloration of bromine is …
