Question

Which of the following can be used as the test for unsaturation with regard to colorchange of reaction? (A) Addition of hydrogen (B) Addition of hydrogen bromide (C) Addition of hypobromous acid (D) Addition of bromine

Addition of bromine can be used as the test for unsaturation with regard to colour change of reaction. e.g.
Unsaturated compound

+ B r_{2} \to

colour of

B r_{2}

rapidly disappears.
i.e. Bromine water is decolourised.

Q. Which of the following can be used as the test for unsaturation with regard to colorchange of reaction?

Addition of hydrogen

Addition of hydrogen bromide

Addition of hypobromous acid

Addition of bromine

Addition of bromine can be used as the test for unsaturation with regard to colour change of reaction. e.g. Unsaturated compound +Br2​→ colour of Br2​ rapidly disappears. i.e. Bromine water is decolourised.
