Chapter 3.3, Problem 6ATS

Interpretation Introduction

Interpretation:

For given compound the more acidic protons to be determined and to be arranged in increasing order.

Concept Introduction

There are two ways to identify the acidity of the compounds,

1. 1) Via comparing ${\text{pK}}_{\text{a}}$ values of the given compounds (quantitative approach)
2. 2) Via study the structures of the acid (qualitative approach)

However, herein we consider only comparing ${\text{pK}}_{\text{a}}$ values.

${\text{PK}}_{\text{a}}$Value:

The ${\text{pK}}_{\text{a}}$ value computes the acidity of an acid. This value depends upon the chemical property and identity of the compound.

${\text{pK}}_{\text{a}}$ ${\text{= - log K}}_{\text{a}}$

Where,

${\text{K}}_{\text{a}}$ is the measure of strength of an acid. If the acid is strong means ${\text{K}}_{\text{a}}$ on the order of ${\text{10}}^{\text{10}}$ and weak means ${\text{K}}_{\text{a}}$ on the order of ${\text{10}}^{-50}.$ Strong acid means ${\text{pK}}_{\text{a}}$ value is low value and Weak acid means ${\text{pK}}_{\text{a}}$ value is high.
