$\begin{array}{ccc}\underset{\underset{+\text{I}}{⏟}}{{\text{CH}}_3}-\underset{\stackrel{\left|\right|}{\text{O}}}{\text{C}}-\text{OH }& \underset{\underset{-\text{I}}{⏟}}{\text{HO}-\stackrel{\underset{\left|\right|}{\text{O}}}{\text{C}}}-\stackrel{\underset{\left|\right|}{\text{O}}}{\text{C}}-\text{OH }& \underset{\underset{-\text{I}}{⏟}}{\text{HO}-\stackrel{\underset{\left|\right|}{\text{O}}}{\text{C}}-}{\text{CH}}_2-{\text{CH}}_2-\stackrel{\underset{\left|\right|}{\text{O}}}{\text{C}}-\text{OH}\\ \text{I }& \text{II }& \text{III}\end{array}$

$Acidic\; strength\propto -\text{I}$

$\propto \frac{1}{+\text{I}}$

Order of acidic strength : II > III > I
