Chapter 6, Problem 6C.12E

Interpretation Introduction

Interpretation:

From the given ${\text{pK}}_{\text{b}}$ values of aniline and 4-chloroaniline which one is stronger base has to be accounted.

Concept Introduction:

The strength of proton accept of a base is called basicity constant and also the basicity constant is said to be as their negative logarithms and which can be represented as follows,

    ${\text{pK}}_{\text{b}}\text{=}{\text{-logK}}_{\text{b}}$

When looking for the strength bases the following points should be noted,

• Weak base always have the smaller value of ${\text{K}}_{\text{b}}$ and has greater value of ${\text{pK}}_{\text{b}}\text{.}$
