TESTS FOR ALCOHOLS AND PHENOLS
Materials:
Test tube - 12
Test tube rack
Test tube holder
Graduated cylinder (100mL) – 1
Alcohol lamp
Crucible tong
Chemicals:
Ethanol
Isopropyl alcohol
Tertiary butyl alcohol
Ferric chloride solution
Sodium metal
Lucas' reagent
Concentrated sulfuric acid
Potassium dichromate solution
Phenol
Millon's reagent
Bromine water
Procedure:
A) Tests for alcohols
1) Sodium metal:
Place 1 ml of each of the following: ethanol, isopropyl alcohol, and tertiary butyl alcohol in
separate test tubes. Add a small piece of sodium metal to the different alcohols. Take note
of the difference in the release of hydrogen gas.
2) Lucas' test:
Place 1 ml of each of the following: ethanol, isopropyl alcohol, and tertiary butyl alcohol in
separate test tubes. Add 1 ml of hydrochloric acid and 1 g of anhydrous zinc chloride to the
different alcohols. Take note of the difference in the formation of cloudy solution.
3) Oxidation:
Place 1 ml of each of the following: ethanol, isopropyl alcohol, and tertiary butyl alcohol in
separate test tubes. Add 10 drops of potassium dichromate and 5 drops of concentrated
sulfuric acid to the different alcohols. Take note of the odor and color of the products.
B) Tests for phenols
1) Bromine water:
Add 1 ml of bromine water to phenol and take note of the color of the precipitate.
2) Ferric chloride test:
Add 5 drops of ferric chloride solution to phenol. Take note of the color formed.
3) Millon's test:
Add 5 drops of Millon's regent to phenol. Take note of the color formed.
