Chapter 6, Problem 6.14E

(a)

Interpretation Introduction

Interpretation:

The relative strengths of Bronsted bases ${\text{OH}}^{\text{-}}{\text{, NH2}}^{\text{-}}{\text{, CH3}}^{\text{-}}$ has to be explained and

Concept Introduction:

A proton is transferred between two molecules, in which one of them is proton acceptor and the other one is proton donor. The proton donor is known as “Bronsted Acid” and the proton acceptor is known as “Bronsted Base”.

Weak Base:

A base dissociates partially into its ions in aqueous solution or water is called “weak base”.

Strong Acid:

A base dissociates completely into its ions in aqueous solution or water is called “strong base”.

(b)

Interpretation Introduction

Interpretation:

${\text{NH}}_{\text{3}}$ is a weak base in water has to be explained.
