WebApr 9, 2016 · Explanation: Ethene and bromine are an addition reaction because ethene is an alkene - it has a double bond. It is easier for new atoms to open the double bond and react there than to remove the hydrogen already attached, and then bond to it, which would be a substitution reaction. Alkenes are more unstable than alkanes, because alkenes … WebThe loss of the hydrogen atom is energetically favorable, due to the temporary loss of aromaticity in the benzene ring. As the FeBr4 approaches, the electron poor hydrogen atom will easily bind with one of the electron rich bromine atoms. This is energetically favorable as well: hydrogen has an electronegetivity of 2.2 as opposed to iron's 1.8.
