Structures which are formed by the electronic displacement of饾洃bonds in a compound. Then the structures generated are known as resonance structures.

Formal charge (F.C) can be defined as the difference number of valence electrons and number of electrons present in the Lewis structure.

$\mathbf{F}\mathbf{.}\mathbf{C}\mathbf{=}[\mathbf{V}\left(\mathbf{electrons}\right)\mathbf{-}\mathbf{L}\left(\mathbf{electrons}\right)]$

V= valence shell

L= electrons present according to Lewis structures

Above can be drawn by the electronic displacement of 饾洃 bonds only.

$\text{F.C=}\left[\text{V}\left(\text{electrons}\right)\text{-L}\left(\text{electrons}\right)\right]$
