what two tests can be used to distinguished a saturated from unsaturated hydrocarbon?
Answers
Answer:
Saturated hydrocarbons : in saturated hydrocarbons all Carbon atoms are bonded to other carbon atoms through carbon - carbon single bonds.
Unsaturated hydrocarbons :In unsaturated hydrocarbons their exists carbon = carbon double bond or carbon =- carbon triple Bond.
Explanation:
CHEMICAL TEST to distinguish between saturated and unsaturated compounds :
1.BY BAEYER'S REAGENT : An alkaline solution of KMnO4 is known as Baeyer's reagent .
Take a small amount of saturated and unsaturated compounds in two different test tubes. A drop of Alkaline solution of KMnO4 is added to both the test tubes. The pink colour of Alkaline KMnO4 solution gets discharged in the test tube containing unsaturated compounds, while the pink colour of Alkaline KMnO4 solution does not get decolorize (no change) in the test tube containing saturated compounds.
2. BY BROMINE WATER : The colour of bromine water is brown.•With bromine water saturated compounds do not decolourise bromine water.•With bromine water unsaturated compounds decolourises the bromine water.
Answer:
The main difference between saturated and unsaturated hydrocarbon is that saturated hydrocarbons contain only single covalent bonds between carbon atoms, whereas unsaturated hydrocarbons contain at least one double or triple covalent bond in the main chain.
Explanation:
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 decolourized by the hydrocarbon, it can then be concluded that the hydrocarbon is unsaturated and if it is not decolourized
