Test For Phenolic Group Functional Group Class 12 Chemi Add 1ml of phenol to the sodium nitrite solution. heat the mixture gently and allow it to cool. add 1ml of concentrated sulfuric acid to it and shake the contents. observe the change in the colour of the solution. dilute the solution with water so that the given compound turns red if a phenolic group is present. Viva questions on test for the functional groups present in organic compounds (unsaturated, alcoholic, phenolic, aldehydic, ketonic, carboxylic and primary amino groups) chemistry practical class 12 test for the functional groups present in organic compounds (unsaturated, alcoholic, phenolic, aldehydic, ketonic, carboxylic and primary amino groups) viva questions with answers.
Phenolic Group Test Class 12th Alcohols And Phenols Chemistry Test for phenol. detection of phenol functional group can be done by following tests –. litmus test. ferric chloride test. phthalein dye test. libermann’s test. bromine water test. any of the above tests can be used to detect the phenol group in a compound. let us discuss all these tests in detail one by one –. Phenol ka test kaise karte haiphenolic group ka test kaise karehow to do test for phenols or phenolic group in hindi. B. phthalein dye test take 0.1 g of organic compound and 0.1 g of phthalic anhydride in a clean dry test tube and add 1 2 drops of conc. h. 2. so. 4. heat the test tube for about 1 minute in an oil bath. cool and pour the reaction mixture carefully into a beaker containing 15 ml of dilute sodium hydroxide solution. Tests for the functional groups present in organic compounds molecules of organic compounds except that of hydrocarbons can be divided into two parts, a reactive part which is referred to as functional group and a skeleton of carbon atoms called alkyl group. the properties of a compound are largely determined by the functional group. different […].
