WebNov 2, 2016 · When bromine reacts with an olefin (which are typically colourless), the orange colour dissipates as it reacts with the bromine. Typically, we use orange-coloured bromine water, and the reaction gives an halohydrin: RCH = CH 2 +Br2(aq) → RCH (OH)CH 2Br + H Br(aq) Bromine is the electrophile, i.e. δ+Br −Brδ−, and it reacts to give a 2∘ ... WebAlkene + water (steam) → alcohol This process is called hydration. It requires a temperature of approximately 300°C and a catalyst. For example: ethene + water (steam) → alcohol …
