Chapter 25, Problem 25.48P

Interpretation Introduction

Interpretation:

The $\text{p}{K}_{\text{a}}$ value of the conjugate acid of benzylamine $\left({\text{C}}_{\text{6}}{\text{H}}_{\text{5}}{\text{CH}}_{\text{2}}{\text{NH}}_{\text{2}}\right)$ to the $\text{p}{K}_{\text{a}}$ values of the conjugate acids of cyclohexanamine $\left(10.7\right)$ and aniline $\left(4.6\right)$ is to be compared.

Concept introduction:

According to Bronsted-Lowry theory, 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. The conjugate base has negative charge or lone pair of electrons present over it.

The basic character of different compounds is compared on the basis of the $\text{p}{K}_{\text{a}}$ values of their conjugate acids.
