Chapter 6, Problem 6A.13E

(a)

Interpretation Introduction

Interpretation:

Lewis structure for ${\text{NH}}_{\text{3}}$ has to be drawn and it has to be identified as Lewis acid or Lewis base.

Concept Introduction:

Electron pair acceptor is known as Lewis acid while electron pair donor is known as Lewis base.  Lewis structure is a simple representation considering the valence electrons present in a molecule.  Electrons are shown using dots around the atoms in a molecule.

(b)

Interpretation Introduction

Interpretation:

Lewis structure for ${\text{BF}}_{\text{3}}$ has to be drawn and it has to be identified as Lewis acid or Lewis base.

Concept Introduction:

Refer part (a).

(c)

Interpretation Introduction

Interpretation:

Lewis structure for ${\text{Ag}}^{\text{+}}$ has to be drawn and it has to be identified as Lewis acid or Lewis base.

Concept Introduction:

Refer part (a).

(d)

Interpretation Introduction

Interpretation:

Lewis structure for ${\text{F}}^{-}$ has to be drawn and it has to be identified as Lewis acid or Lewis base.

Concept Introduction:

Refer part (a).

(e)

Interpretation Introduction

Interpretation:

Lewis structure for ${\text{H}}^{-}$ has to be drawn and it has to be identified as Lewis acid or Lewis base.

Concept Introduction:
