Chapter 10, Problem 21E

Interpretation Introduction

(a)

Interpretation:

Interpretformal charge on central O present in ${\text{O}}_{\text{2}}$.

Concept introduction:

Formal charge is the charge present on the bonded atom in the covalent molecule. Formal charge can be determined as:

$\text{FC = VE – LE – bond pair}$

Here:

• FC = Formal charge on bonded atom.
• VE = Valence electrons present in octet of the bonded atom.
• LE = Total number of lone electrons on bonded atom.
• Bond pair = Total number of bonds linked to the atom.

Interpretation Introduction

(b)

Interpretation:

Interpretformal charge on Al present in ${\text{AlH}}_{\text{4}}{}^{\text{-}}$.

Concept introduction:

Formal charge is the charge present on the bonded atom in the covalent molecule. Formal charge can be determined as:

$\text{FC = VE – LE – bond pair}$

Here:

• FC = Formal charge on bonded atom.
• VE = Valence electrons present in octet of the bonded atom.
• LE = Total number of lone electrons on bonded atom.
• Bond pair = Total number of bonds linked to the atom.

Interpretation Introduction

(c)

Interpretation:

Interpretformal charge on Cl present in ${\text{ClO}}_{\text{3}}{}^{-}$.

Concept introduction:

Formal charge is the charge present on the bonded atom in the covalent molecule. Formal charge can be determined as:

$\text{FC = VE – LE – bond pair}$

Here:

• FC = Formal charge on bonded atom.
• VE = Valence electrons present in octet of the bonded atom.
• LE = Total number of lone electrons on bonded atom.
• Bond pair = Total number of bonds linked to the atom.

Interpretation Introduction

(d)

Interpretation:

Interpretformal charge on Si present in ${\text{SiF}}_{\text{6}}{}^{\text{2-}}$.

Concept introduction:

Formal charge is the charge present on the bonded atom in the covalent molecule. Formal charge can be determined as:

$\text{FC = VE – LE – bond pair}$

Here:

• FC = Formal charge on bonded atom.
• VE = Valence electrons present in octet of the bonded atom.
• LE = Total number of lone electrons on bonded atom.
• Bond pair = Total number of bonds linked to the atom.
