Observe the following structure
The formal charges on the atoms $1,2,3$ respectively are
$+1,0,-1$
$0,0,-1$
$-1,0,+1$
$0,0,0$
Solution
The Formal charge can be calculated by this Formula
$\begin{aligned} \text { Formal charge }= & {\left[\begin{array}{l}\text { Total number of } \\ \text { Valence electron } \\ \text { in the free state }\end{array}\right]-\left[\begin{array}{l}\text { Total number of } \\ \text { non }- \text { Bonding (lone } \\ \text { pair) electron }\end{array}\right] } \\ & -\frac{1}{2}\left[\begin{array}{c}\text { Total number of Bonding } \\ (\text { shared) electrons }\end{array}\right]\end{aligned}$
For atom $1 \Rightarrow 6-41 / 2[4]=0$
Atom $2 \Rightarrow 5-2-1 / 2[6]=0$
Atom $3 \Rightarrow 6-6=1 / 2[2]=-1$
