Chapter 2, Problem 11CTQ

(a)

Interpretation Introduction

Interpretation:

Whether the formal charge of each atom in ${\text{CH}}_4$ is equal to zero or not should be confirmed.

Concept Introduction :

Formal Charge = Group Number − Number of lines − Number of dots

Group Number refers to the column number on the periodic table.

Number of lines indicates the number of line bonds to the atom in the Lewis structure or it shows the number of bonded pair of electrons.

Number of dots represent the number of non-bonded electrons on an atom in the Lewis structure

(b)

Interpretation Introduction

Interpretation:

Whether the formal charge of each atom in ${\text{H}}_{\text{2}}\text{O}$ is equal to zero or not should be confirmed.

Concept Introduction :

Formal Charge = Group Number − Number of lines − Number of dots

Group Number refers to the column number on the periodic table.

Number of lines indicates the number of line bonds to the atom in the Lewis structure or it shows the number of bonded pair of electrons.

Number of dots represent the number of non-bonded electrons on an atom in the Lewis structure

(c)

Interpretation Introduction

Interpretation:

Whether the formal charge of each atom in $\text{HCN}$ is equal to zero or not should be confirmed.

Concept Introduction :

Formal Charge = Group Number − Number of lines − Number of dots

Group Number refers to the column number on the periodic table.

Number of lines indicates the number of line bonds to the atom in the Lewis structure or it shows the number of bonded pair of electrons.

Number of dots represent the number of non-bonded electrons on an atom in the Lewis structure

(d)

Interpretation Introduction

Interpretation:

Whether the formal charge of each atom in $\text{HBr}$ is equal to zero or not should be confirmed.

Concept Introduction :

Formal Charge = Group Number − Number of lines − Number of dots

Group Number refers to the column number on the periodic table.

Number of lines indicates the number of line bonds to the atom in the Lewis structure or it shows the number of bonded pair of electrons.

Number of dots represent the number of non-bonded electrons on an atom in the Lewis structure

(e)

Interpretation Introduction

Interpretation:

Whether the formal charge of each atom in ${\text{H}}_2\text{CO}$ is equal to zero or not should be confirmed.

Concept Introduction :

Formal Charge = Group Number − Number of lines − Number of dots

Group Number refers to the column number on the periodic table.

Number of lines indicates the number of line bonds to the atom in the Lewis structure or it shows the number of bonded pair of electrons.

Number of dots represent the number of non-bonded electrons on an atom in the Lewis structure
