Chapter 2.11, Problem 2.15P

(a)

Interpretation Introduction

To determine: The reactions of the given compounds with water.

Interpretation: The reactions of the given compounds with water are to be stated.

Concept introduction: When an acid donates a proton, the species formed is known as conjugate base and when the base accepts a proton, the species formed is known as conjugate acid.

(b)

Interpretation Introduction

To determine: The corresponding $\text{p}{K}_{\text{a}}$ values of the given structures with an explanation.

Interpretation: The $\text{p}{K}_{\text{a}}$ values of the given structures are to be matched and the reason is to be explained.

Concept introduction: The equilibrium constant of an acid dissociation reaction depends on the strength of an acid involved in the reaction. The $K_{\text{a}}$ value is large for strong acids and small for weak acids. The $\text{p}{K}_{\text{a}}$ value of weak acid is calculated by the formula,

$\text{p}{K}_{\text{a}}=-{\log }_{10}{K}_{\text{a}}$
