Chapter 25, Problem 25.21P

Interpretation Introduction

(a)

Interpretation: Among the given pair of compounds, the more basic compound is to be determined.

Concept introduction: An equilibrium constant ($K_{\text{a}}$ ) is used to measure the acidity of an acid. There is an inverse relationship between the acidity of an acid and its $\text{p}{K}_{\text{a}}$ value. Higher the value of $\text{p}{K}_{\text{a}}$, weaker is the acid.
