The powerful electron-withdrawing property of a carbonyl group increases the acidity of a-protons (i.e., protons attached to a carbon that is adjacent to the carbonyl group). The effect varies depending on what else is attached to the carbonyl, and whether there is a second carbonyl group attached to the a-carbon. Rank the structures from highest acidity (lowest pK, value) to lowest acidity (highest pK, value). The acidic hydrogen is indicated in blue in each structure. Highest acidity Lowest acidity Answer Bank CH CH H3C CH3 H H. H;C H. H CH3 CH3
