  World of Chemistry, 3rd edition, Chapter 12, Problem 64A , additional homework tip  1

Structure of OF2is:

  World of Chemistry, 3rd edition, Chapter 12, Problem 64A , additional homework tip  2

Explanation of Solution

In CO2 , central atom carbon is bonded to two oxygen atoms by double bonds.

In OF2 , central atom oxygen is bonded to two fluorine by single bonds.

(b)

Interpretation Introduction

Interpretation: The molecular geometry of given molecules is to be written.

Concept introduction:

Structure of molecule can be drawn using VSEPR theory. The total number of bonding and non-bonding pairs of electrons tells about the geometry of the molecule.

Answer to Problem 64A

Geometry of CO2 : linear

Geometry of OF2: Tetrahedral

Explanation of Solution

In CO2 , central atom carbon is bonded to two oxygen atoms by double bonds. There are two pairs of valence electrons around central atom. Therefore, geometry is linear.

In OF2 , central atom oxygen is bonded to two fluorine by single bonds. There are four pairs of valence electrons around the central atom. Therefore, geometry is tetrahedral

(c)

Interpretation Introduction

Interpretation: The molecular geometry of given molecules is to be written.

Concept introduction:

Structure of molecule can be drawn using VSEPR theory. The total number of bonding and non-bonding pairs of electrons tells about the geometry and molecular structure of the molecule.

Answer to Problem 64A

Structure (shape) of CO2 : linear

Structure (shape) of OF2: Bent

Explanation of Solution

In CO2 , central atom carbon is bonded to two oxygen atoms by double bonds. There are two bonding pairs of valence electrons around central atom. Therefore, shape is linear.

In OF2 , central atom oxygen is bonded to two fluorine by single bonds. There are four pairs of valence electrons around the central atom in which two are bonding and two are non-bonding. Therefore, geometry is tetrahedral and the shape is bent

(d)

Interpretation Introduction

Interpretation:

The shape of given molecules is to be compared.

Concept introduction:

Two molecules having same general formula can sometimes have same shapes and sometimes have different shapes. It depends on type of pair of valence electrons around the central atom.

(d)

Expert Solution

Answer to Problem 64A

  CO2 and OF2 have different shape because both have different number of valence electrons around the central atom.

Explanation of Solution

In CO2 , central atom carbon is bonded to two oxygen atoms by double bonds. There are two bonding pairs of valence electrons around central atom. Therefore, shape is linear.

In OF2 , central atom oxygen is bonded to two fluorine by single bonds. There are four pairs of valence electrons around the central atom in which two are bonding and two are non-bonding. Therefore, geometry is tetrahedral and the shape is bent
