What is the functional group of propanoic acid? How do we know if it's soluble in water or insluble in water using the flowchart that is attached. which test should be performed using the flowchart. Is propanoic acid a ketone, aldehyde, ester or alcohol and how did you know?what would be the most efficient series of solubility and functional group tests that would identify the functional group? Also what could be the sources of error in this experiment? What could occur that would give false positives, false negatives, or incorrect interpretations?
