We’re being asked to rank the indicated protons in order of decreasing acidity.
Recall that pKa is the measure of the acidity of a compound: lower pKa → more acidic.
Rank the indicated protons in decreasing order of acidity.
(A) II > I > III
(B) I > III > II
(C) II > III > I
(D) I > II > III
(E) III > II > I
