Test for Alcoholic Group

Sr. No	Experiment	Observation	Inference
1.	Ceric Ammonium nitrate Test: To the organic compound 1 ml of ceric ammonium nitrate was added.	Red color was obtained	R – OH group is present
	2 R – OH + (NH4)2 Ce (No3)6   à   [(ROH)2 Ce ( No3)4] + 2 NH4 No3
`2.	Sodium metal Test: To the organic compound in a dry test tube a small piece of sodium metal was added.	Bubbles of H2 gas were evolved	R – OH group is present
	2 R- OH + 2 Na   à   2 R – O – Na+ + H2↑
3.	Ester formation Test: To the organic compound 1 ml glacial acetic acid & 1 – 3 drops of conc. H2So4 was added. The mixture was wormed in water bath for 10 – 15 minutes cool & poured the content	Pleasant smell due to presence of ester.	R – OH group is present
	R – OH + R’ – C – OH   ß à  R’ – C – O – R + H2O

 

Conclusion:

On the basis of above test we conclude that the given organic compound contained alcoholic [R – OH] group.
