Unsaturated organic compounds are identified by decolourization of
- silver bromine and potassium tetraoxomanganate (VII) solutions
-
bromine water and acidified potassium tetraoxomanganate (VII) solution
- silver bromide solution and bromine water
- bromine water and alkaline potassium tetraoxomanganate (VII) solution
The correct answer is: B
Explanation
Unsaturated organic compounds are identified by the decolorization of bromine water.The acidified potassium manganate(VII) solution oxidizes the alkene by breaking the carbon-carbon double bond and replacing it with two carbon-oxygen double bonds. The products are known as carbonyl compounds because they contain the carbonyl group, C=O. Thus, they are decolourized as well.
