How do scientists test if phenol is acidic or basic?
Scientists use litmus paper to test whether the given solution is acidic or basic. Red litmus paper turns blue while blue litmus paper remains unchanged in the presence of a base. Phenol turns blue litmus paper red. This shows that phenol is acidic in nature. Carboxylic acid also gives this test.
How to detect phenolic functional group?
Any of the following tests can be carried out to detect the phenolic functional group. Scientists use litmus paper to test whether the given solution is acidic or basic. Red litmus paper turns blue while blue litmus paper remains unchanged in the presence of a base. Phenol turns blue litmus paper red. This shows that phenol is acidic in nature.
How to detect carboxylic functional group?
Any of the following tests can be carried out to detect the carboxylic functional group. The carboxylic acid turns blue litmus red. Because the hydroxyl group present in -COOH is far more acidic than in alcohol. The chemical reaction is given below. Note: If the colour of the blue litmus paper changes to red, then a carboxylic group is present.
What is the chemical reaction between carboxylic acid and phenol?
The chemical reaction is given below. Note: This test is used to distinguish between carboxylic acid from phenol. Phenol does not give this test. Carboxylic acid reacts with alcohol in the presence of concentrated sulphuric acid and forms a pleasant smelling ester. This reaction is known as esterification. The chemical reaction is given below.
