Which of the following can be used as the test for unsaturation with regard to colour change of reaction?
- A Addition of hydrogen
- B Addition of hydrogen bromide
- C Addition of hypobromous acid
- D Addition of bromine
Answer & Solution
Correct Answer
(D) Addition of bromine
Step-by-step Solution
Detailed explanation
Addition of bromine can be used as the test for unsaturation with regard to colour change of reaction. e.g. Unsaturated compound \(+\mathrm{Br}_2 \rightarrow\) colour of \(\mathrm{Br}_2\) rapidly disappears. i.e. Bromine water is decolourised.
