Chapter 7, Problem 28QAP
Interpretation Introduction

(a)

Interpretation:

The formal charge on oxygen atom in HOF needs to be determined.

Concept introduction:

  • Formal charge is the charge associated with an atom in a given molecule. It is representative of the electron distribution in a molecule
  • It takes into account the number of valence electrons associated with the neutral atom and compares it to the number of electrons surrounding that atom in the given molecule.
  • Mathematically, formal charge (FC) can be calculated as follows:

FC = VEunshared electronsnumber of bonds --------(1)

where VE = valence electrons of the atom

Interpretation Introduction
