1 Unknown #2 Type of compound: Aldehyde Alcohol Amine Ketone

2 Procedure 1. Physical Properties Melting point or boiling point
2. Functional Group Infrared spectrum NMR Spectrum Solubility Classification Tests 3. Solid Derivative

3 Measure boiling point of liquids

4 Functional Group - No Yes Alcohol Amine Aldehyde Ketone CrO3 + Yes No
Carbonyl Group ( cm-1)? No Yes Alcohol Amine Aldehyde Ketone Broad OH in IR CrO3 - + Yes No Alcohol Aldehyde Ketone Amine (Basic?) cm-1 Yes No Primary or Secondary Tertiary

5 Chromic Acid Test CrO3/H2SO4 in acetone Cr3+ H2CrO4 green red

6 Iodoform Test Reagent: NaOH and I2 (NaOI)

7 Amines 1. Odor 2. If not soluble in water they may dissolve in dilute aqueous acid (HCl). 3. Water solutions of amines are basic to litmus.
