Question
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:
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.
