Distinction test for functional groups
- 1. DISTINCTION TEST FOR FUNCTIONAL GROUPS A PRESENTATION BY RAKSHIT DOGRA Presentation on
- 2. CONTENTS OF THIS PRESENTATION FUNCTIONAL GROUPS AND THEIR TESTS OF DISTINCTION Tests for Unsaturation There are two tests for determining unsaturation in an organic compound. Tests for Phenolic group Phenols are compounds containing a hydroxyl group attached to an aromatic ring Tests for Aldehydic and Ketonic Groups Aldehydes and Ketones are compounds containing carbonyl group Tests for Carboxylic group Carboxylic acids are organic compounds containing carboxyl functional group Tests for Amines Amines are derivatives of ammonia in which one or more hydrogen atoms are replaced by alkyl or aryl groups.
- 3. INTRODUCTION What are functional Groups? The atom or group of atoms that replaces hydrogen atoms from hydrocarbon are called functional groups. They may be –OH, -COOH, -CO, -CHO, -Cl, -COCl, -COOR etc. Functional groups are responsible for the characteristics of a molecule.
- 4. Tests for Unsaturation 01 Bromine Test There are two tests for determining unsaturation in an organic compound.
- 5. Tests for Unsaturation 02 Baeyer’s Test (Alkaline KMnO4 Test)
