In a given resonance structure, the O atom that forms double bond has formal charge of 0 and the remaining 3 O atoms have formal charge of -1 each.
In the resonance hybrid, a total of -3 charge is distributed over 4 O atoms. Thus the formal charge of each O atom is

−3
=−0.75.
Note:
To calculate the formal charge, the following formula is used.
Formal Charge = [Number of valence electrons on atom] – [non-bonded electrons + number of bonds]
For O atom that forms double bond with P atom,
Formal Charge = 6] – [4 +2] = 0.
For O atom that forms single bond with P atom,
Formal Charge = 6] – [6 +1] =− 1.
The formal charge on the oxygen in ClOF4+ is -4.
- The formal charge on an atom in a molecule is calculated as the difference between the number of valence electrons the neutral atom would have and the number of electrons assigned to that atom in the Lewis structure of the molecule.
- In the case of ClOF4+, the oxygen atom has 6 valence electrons. In the Lewis structure, it is bonded to one chlorine and four fluorine atoms, so it has a total of 6 + 4 = 10 electrons assigned to it.
- Hence, the formal charge on the oxygen in ClOF4+
- 6 - 10 = -4.
- It is important to note that the formal charge on an atom can be used to help predict the most likely Lewis structure for a molecule, but it does not necessarily reflect the actual distribution of electrons in a molecule.
