Chapter 16, Problem 16.143SP

Interpretation Introduction

(a)

Interpretation:

The stronger Lewis acid from ${\text{BF}}_{\text{3}}$ and ${\text{BH}}_{\text{3}}$ needs to be identified.

Concept introduction:

Lewis acid is an electron-pair acceptor to any molecule or the ion that can accept pair of non-bonding valence electron while Lewis base donates the pair of non-bonding electrons. In the general terms, Lewis acid is considered as an acceptor of electron pairs, whereas the Lewis base is considered as a donor of electron-pairs.

Interpretation Introduction

(b)

Interpretation:

The stronger Lewis acid from ${\text{SO}}_{\text{2}}$ and ${\text{SO}}_{\text{3}}$ needs to be identified.

Concept introduction:

Lewis acid is an electron-pair acceptor to any molecule or the ion that can accept pair of non-bonding valence electron while Lewis base donates the pair of non-bonding electrons. In the general terms, Lewis acid is considered as an acceptor of electron pairs, whereas the Lewis base is considered as a donor of electron-pairs.

Interpretation Introduction

(c)

Interpretation:

Explain the stronger Lewis acid from ${\text{Sn}}^{\text{2+}}$ and ${\text{Sn}}^{\text{4+}}$.

Concept introduction:

Lewis acid is an electron-pair acceptor to any molecule or the ion that can accept pair of non-bonding valence electron while Lewis base donates the pair of non-bonding electrons. In the general terms, Lewis acid is considered as an acceptor of electron pairs, whereas the Lewis base is considered as a donor of electron-pairs.

Interpretation Introduction

(d)

Interpretation:

Explain the stronger Lewis acid from ${\text{CH}}_{\text{3}}{}^{\text{+}}$ and ${\text{CH}}_{\text{4}}$.

Concept introduction:

Lewis acid is an electron-pair acceptor to any molecule or the ion that can accept pair of non-bonding valence electron while Lewis base donates the pair of non-bonding electrons. In the general terms, Lewis acid is considered as an acceptor of electron pairs, whereas the Lewis base is considered as a donor of electron-pairs.
