- Carboxylic acids are versatile organic compounds, They have excellent physical and chemical properties. The carboxylic acid chemical structure contains a carbonyl functional group and a hydroxyl group. It interacts easily with polar compounds and contributes to many important chemical reactions. The carboxylic acid is the most important functional group that present C O. THEORY Carboxylic acids have tendency to donate protons and they act as acids. It is this property which is helpful in the identification of a - COOH group. Qualitative tests that can be performed to identify carboxylic functional group include litmus test, sodium bicarbonate test or sodium hydrogen carbonate test, ester test and Fluorescein test. Litmus test. The carboxylic acid turns blue litmus paper red. Because the hydroxyl group present in - COOH is far acidic than in alcohol. The chemical reaction is given below.
