Solution
The correct option is A Bromine water
The bromine test is a qualitative test for the presence of unsaturation (carbon-to-carbon double or triple bonds) and phenols. An unknown sample is treated with a small amount of elemental bromine in an organic solvent, being as dichloromethane or carbon tetrachloride. Presence of unsaturation and/or phenol in the sample is shown by disappearance of the deep brown coloration of bromine when it has reacted with the unknown sample.
