WebIn the experiment entitled Steam Distillation, you demonstrated that eugenol has one or more carbon-carbon double bonds by reacting it with bromine, Br 2, and observing the discharge of the reddish-brown color of bromine as each drop reacted with the double bond in eugenol. At that time, you were not asked to specify the structure of the product. WebBromine test: would confirm the presence of an alkene (double bond) functional group in Eugenol by the red-brown colour of the Bromine turning clear. This would be due to the addition reaction caused. This was demonstrated pictorially in pre-lab with the double bond being broken and 2 x Bromine adding to the Eugenol structure.
