All the molecules contain a polar group. However, the molecule that should be most soluble in water is propanoic acid. Why?
Explanation:
Butanoic acid has the shortest pendant alkyl chain. For this sole reason we would predict that it should give greater aqueous solubility. This is a prediction.
As a physical scientist, you should look up the literature to see if this prediction is true.
