Question

give a chemical test to distinguish between saturated and unsaturated hydrocarbon

Answer 1

Testing. To test whether the hydrocarbon is unsaturated one would typically use the bromine test, which involves the addition of bromine water to the hydrocarbon in question; if the bromine water is decolorized by the hydrocarbon, it can then be concluded that the hydrocarbon is unsaturated.

Answer 2

Use bromine water which is red brown in color... When we put it in unsaturated hydrocarbons it become colorless and in saturated hydrocarbon it did not shows any changes...
