Butter is a saturated carbon compound while cooking oil is an unsaturated carbon compound. An unsaturated compound decolourises bromine water, while a saturated compound cannot decolourise it. So we can distinguish chemically between a cooking oil and butter by the bromine water. Add bromine water to a little of cooking oil and butter taken in separate test-tubes.
(1)Cooking oil decolourises bromine water showing that it is an unsaturated compound.
(2)Butter does not decolourise bromine water showing that it is a saturated compound.
