Question

Test one functional group in the given unknown organic compound L​

Answer 1

Answer:

Test of a given organic compound

Explanation:

Tests for Unsaturation

There are two tests for determining unsaturation in an organic compound.

1. Bromine Test

In this test, the orange-red colour of bromine solution disappears when it is added to an unsaturated organic compound (unsaturated hydrocarbon).

2. Baeyer’s Test (Alkaline KMnO4 Test)

In this test, pink colour of KMnO4 disappears, when alkaline KMnO4 is added to an unsaturated hydrocarbon. The disappearance of pink colour may take place with or without the formation of brown precipitate of MnO2.

Tests for Alcoholic Group

Alcohols are compounds in which the hydroxyl group (-OH) is linked to aliphatic carbon chain or in the side chain of an organic compound. Depending upon the number of hydroxyl group, alcohols are classified as mono (contain only one –OH group), di (contain two –OH groups) and trihydric (contains three –OH groups).
