Chapter 10.4, Problem 2QQ

Interpretation Introduction

Interpretation:

From the given pairs of bases, the pair of weak bases has to be identified.

Concept Introduction:

Weak base:

A base is substance which accepts ${\text{H}}^{\text{+}}$ ions.  Weak base will not dissociate completely when dissolved in water, $\text{100\%}$ ionisation is not possible.

Example:

  ${\text{NH}}_{\text{3}}{\text{ + H}}_{\text{2}}\text{O }\underset{}{\overset{}{\rightleftharpoons }}{\text{ NH}}_{\text{4}}{}^{\text{+}}{\text{ + OH}}^{\text{-}}$
