Two hydrocarbons X and Y were treated with bromine water. X decolorised the solution and Y did not not. Which class of compound does Y belong?
Answer Details
When hydrocarbons react with bromine water, the bromine is added across the double or triple bond of an unsaturated hydrocarbon. This reaction is called addition reaction. Alkenes and alkynes are unsaturated hydrocarbons which can undergo addition reactions while alkanes are saturated hydrocarbons which cannot undergo addition reactions. Hence, the hydrocarbon Y that did not decolorize the solution is an alkane.
