Question

Two organic compounds A and B are given to you. Of these two, one is

saturated and the other is unsaturated. How will you identify which compound

is unsaturated?​

Answer 1

. If the iodine changes from brown to clear the lipid is unsaturated. If the iodine does not change colors the lipid is saturated.

Answer 2

We can identify which compound is unsaturated by Bromine test.

• In bromine test we add bromine to each of the compounds. Bromine is initially brown in color but when it mixes with unsaturated compounds, it loses it's color.
• While bromine does not change it's color when it is added to saturated compounds.
• There are many other tests other than Bromine test to differentiate between unsaturated and saturated compounds like Baeyer's test.
