Expert Solution
Step 1

2-oxopropanoic acid is a strong acid than 3-oxobutanoic acid because of the electron withdrawing inductive effect of the adjacent carbonyl group. This effect stabilizes the anionic conjugate base of 2-oxopropanoic acid. This means that 3-oxobutanoic acid has a pKa of 3.58 and 2-oxopropanoic acid has a pka of 2.49.
