Exercises 1. Consider the following a. Rank the acids (A-E) in order of most acidic to least acidic. For compounds with multiple acidic protons, only consider the acidity of the first proton. (put the letter corresponding to the acid in order from most acid to least acidic in the following boxes): b. Draw the structure of dianions (i.e., after deprotonating the second most acidic proton) for molecules \( \mathrm{C} \) and \( \mathrm{E} \). Make sure to indicate any formal charges on any atoms within each structure. Structure of dianion of \( \mathbf{C}\left(\mathrm{HPO}_{4}{ }^{2-}\right) \quad \) Structure of dianion of \( \mathbf{E}\left(\mathrm{H}_{2} \mathrm{P}_{2} \mathrm{O}_{7}{ }^{2-}\right) \) c. Which compound, C or E, do you think will have the lower second pKa (i.e., the pKa of the second most acidic proton)?
