Chapter 6, Problem 6C.2AST

(a)

Interpretation Introduction

Interpretation:

The strongest acid among $\text{HF}$ and $\text{HIO}$ has to be chosen considering the $K_a$ values.

Concept Introduction:

Weaker acid due to proton transfer has a stronger conjugate base.  If the base has a large basicity constant, then the conjugate acid will have small $K_a$ value.  If the acid has a large acidity constant, then the conjugate base will have small $K_b$ value.  If the acid has more $K_a$ value, then the acid will be stronger.  If the base has more $K_b$ value, then the base will be stronger.

(b)

Interpretation Introduction

Interpretation:

The strongest base among ${\text{C}}_{\text{6}}{\text{H}}_{\text{5}}{\text{CO}}_{\text{2}}{}^{-}$ and ${\text{CH}}_{\text{2}}{\text{ClCO}}_{\text{2}}{}^{-}$ has to be chosen considering the $K_b$ values.

(c)

Interpretation Introduction

Interpretation:

The strongest base among ${\text{C}}_{\text{6}}{\text{H}}_{\text{5}}{\text{NH}}_{\text{2}}$ and ${{\text{(CH}}_{\text{3}}\text{)}}_{\text{3}}\text{N}$ has to be chosen considering the $K_b$ values.

Interpretation Introduction

Interpretation:

The strongest acid among ${\text{C}}_{\text{6}}{\text{H}}_{\text{5}}{\text{NH}}_{\text{3}}{}^{\text{+}}$ and ${{\text{(CH}}_{\text{3}}\text{)}}_{\text{3}}{\text{NH}}^{\text{+}}$ has to be chosen considering the $K_a$ values.
