Question

In O molecule, the formal charge on the central O-atom is

• A. 0
• B. -1
• C. -2
• D. 1

Answer 1

Answer: (D)

1

Answer 2

Lewis gave the structure of O molecule as Using the relation, Formal charge = [Total no. of valence electrons in the free atom] - [Total no. of non-bonding (lone pair) electrons] -$\frac{1}{2}$ [Total no. of bonding (shared) electrons] The formal charge on central O -atom i.e., no. 1 $\quad\quad\quad\quad$ $=6-2-\frac{1}{2}\left(6\right)=+1$
