Chapter 8, Problem 8.11P

(a)

Interpretation Introduction

Interpretation:

The molecular class, geometry and bond angle of ${\text{OF}}_{\text{2}}$ has to be given.

Concept Introduction:

Molecules can be classified by introducing the terminologies.

Let A represent a central atom, X represent a bonded atom to the central atom and E represent the lone pair of electrons on the central atom.  Thus the centre atom in a molecule can be classified as ${\text{AX}}_{\text{m}}{\text{E}}_{\text{n}}$.

(b)

Interpretation Introduction

Interpretation:

The molecular class, geometry and bond angle of ${\text{KrF}}_4$ has to be given.

Concept Introduction:

Refer to part (a).

(c)

Interpretation Introduction

Interpretation:

The molecular class, geometry and bond angle of ${\text{CF}}_4$ has to be given

Concept Introduction:

Refer to part (a).

(d)

Interpretation Introduction

Interpretation:

The molecular class, geometry and bond angle of ${\text{GeCl}}_{\text{4}}$ has to be given.

Concept Introduction:

Refer to part (a).
