How will you distinguish between saturated and unsaturated hydrocarbons ?

Text Solution

Verified by Experts

Flame test : Saturated hydrocarbons give a clean blue flame on burning but when unsaturated hydrocarbons burn, they give a yellow flame with lots of black smoke.
ii. Bromine water test : Saturated hydrocarbons do not contain carbon-carbon double or triple bonds. Therefore, they do not undergo addition reactions with broine water. Unsatureated hydrocarbons contain carbon-carbon double or triple bonds. Therefore, they undergo addition reactions with bromine water. Hence, they decolourize bromine water.
iii. Tincture iodine test : Saturated hydrocarbons do not contain carbon-carbon double or triple bonds. Therefore, they do not undergo addition reactions with iodine present in tincutre iodine. Hence, they do not decolourize tincutre iodine solution-carbon double or triple bonds. Therefore, they undergo addition reactions with iodine present in tincture iodine. Hence, they decolourize tincture iodine solution.
