Aspirin/Ibprofen Solubility in Water vs Benzoic Acid

[Ryan_77]

Would you expect to that Aspirin and Ibprofen are more or less soluble in water than benzoic acid? ( I believe it has something to do with the polarity of the bonds but I am unsure how to choose between the two.)

Look at the structures. If you put a bunch of greasy groups on the aromatic group what will happen to solubility in water?
