3.17 In the following compound, two protons are clearly identified. Determine which of the two is more acidic. Draw all of the resonance structures of each conjugate base, and after comparing the conjugate bases, you must consider the following question: Is it more stabilizing for a negative charge to be spread out over one oxygen atom and three carbon atoms or to be spread out over two oxygen atoms? Take a look at the pKa values listed in Table 3.1 to answer this
