Chapter 10, Problem 20E

Interpretation Introduction

Interpretation:

The cases in which formal charge is not minimum or approaches to 0 should be determined.

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.
