Reaction of eugenol with bromine
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. Webbromine (red) in dichloromethane decolorizes as br2 reacts with double bond to form colorless compound (positive = disappearance of red br2 color); resulted in yellow test …
