Chapter 20, Problem 23P

Interpretation Introduction

Interpretation:

The given compound should be arranged in the order of strongest acid to weak acid.

Concept Introduction:

The acidic strength of compound depends upon its ability to give proton in aqueous solution.  The dissociation constant of strong acids has high values than weak acids.  The $\text{p}{K}_{\text{a}}$ value is determined by taking the negative log of dissociation constant.  Higher the $K_{\text{a}}$ value, lower is the $\text{p}{K}_{\text{a}}$ value and higher is the acidic strength.
