Chapter 3.3, Problem 5ATS
Interpretation Introduction

Interpretation:  For given compound the most acidic proton to be determined.

Concept Introduction

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

  1. 1) Via comparing pKa values of the given compounds (quantitative approach)
  2. 2) Via study the structures of the acid (qualitative approach)

However, herein we consider only comparing pKa values.

PKa Value: The pKa value computes the acidity of an acid. This value depends upon the chemical property and identity of the compound.

pKa = - log Ka

Where,

Ka is the measure of strength of an acid. If the acid is strong means Ka on the order of 1010 and weak means Ka on the order of 1050. Strong acid means pKa value is low value and Weak acid means pKa value is high.
