Question

The formal charge of S atom in $S{O}_3$ is :

• A. $+2$
• B. $+1$
• C. $0$
• D. $-1$

Answer 1

The correct option is C $0$

$\text{Formal charge}=\text{Number of Valence electrons}-\text{Number of Non-Bonding electrons}-\frac{\text{Number of Bonding}{e}^{-}}{2}$

Structure of $S{O}_3$ is given as:

Formal Charge $=6-0-\frac{12}{2}=6-6=0$
