WebThis indicates that many electrons are clinging to double bonds. The double bond is attractive to molecules known as electrophiles because they enjoy receiving electrons. There is an electrophilic reaction as a result. For instance, the propene double bond attracts the bromine molecule. 1,2-Dibromopropene is created when bromine and propene react. 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 …
WebJan 23, 2024 · This page looks at the reaction of the carbon-carbon double bond in alkenes such as ethene with halogens such as chlorine, bromine and iodine. This is called halogenation. Reactions where the chlorine or bromine are in solution (for example, "bromine water") are slightly more complicated and are treated separately at the end. WebBromine water (Br 2): It is used to identify unsaturation in an organic compound and undergoes an addition reaction, to give a decolorized solution.; It is a yellowish-red color …
WebThe reaction of alkenes with bromine water: C 2 H 4 + Br 2 ———-> C 2 H 4 Br 2 ethene + bromine———> 1, 2-dibromoethane. The bromine has added across the double bond. Bromine water does not react with saturated compounds (alkanes) because they do not have a double bond to ‘open up’.
