Identify the functional group Phenolic (Ar-OH)

S.No.

Experiment

Observations

Inference

1

Nature of the compound – Put a drop of loquid or water solution on moist blue litmus paper

Litmus paper truns red

Organic compound is acidic in nature

-COOH or Ar-OH may be

2

Burning Test : Take some organic compount on copper wire and bring it in to flame

The compound bruns with non-sooty blue flame

Compound is aliphatic

3

Detection of element–

Lassaigne solution + NaOH + freshly prepared FeSO₄ solution

Green ppt

Add few drops of dil H₂SO₄

Solution does not turns green or blue

N absent

4

Test for Functional group –

FeCl3 test Aqueous solution of organci compound + neutral FeCl₃ Solution

Solutionn turns green

Phenolic

(Ar-OH) group present

5

Libermann Nitrsso Test

Organic compound + NaNO₂ + dil. H₂SO₄

Dilute the solution with water

Above red solution + NaOH solution

Blue coloured solution is obtained

The solution red

The solution becomes blue

Phenolic

(Ar-OH) group comfirmed
