Chapter 7, Problem 80QRT

(a)

Interpretation Introduction

Interpretation:

Molecules which have electron-region geometry same as that of molecular-geometry has to be given.

Concept Introduction:

Lewis structures are diagrams that represent the chemical bonding of covalently bonded molecules and coordination compounds.

Electron geometry is the shape of a molecule predicted by considering both bond electron pairs and lone pair of electrons.

(b)

Interpretation Introduction

Interpretation:

Nonpolar molecules have to be identified.

(c)

Interpretation Introduction

Interpretation:

Molecules which have linear geometry have to be identified.

(d)

Interpretation Introduction

Interpretation:

Molecules which have triangular planar geometry have to be identified.

(e)

Interpretation Introduction

Interpretation:

The boxes which have molecules having central atom with ${\text{sp}}^3$ hybridisation have to be given.

(f)

Interpretation Introduction

Interpretation:

The boxes which have molecules having central atom with ${\text{sp}}^2$ hybridisation have to be given.

(g)

Interpretation Introduction

Interpretation:

The box which contains molecules with both dipole-dipole and hydrogen bonding forces has to be given.
