Chapter 19, Problem 19.49P

Draw all resonance structures of the conjugate bases formed by removal of the labeled protons $\left({\text{H}}_{\text{a}}\text{,}{\text{H}}_{\text{b}}\text{,}\text{and}{\text{H}}_{\text{c}}\right)$ in $\text{cyclohexane}-1,3-\text{dione}$ and acetanilide. For each compound, rank these protons in order of increasing acidity and explain the order you chose.
