In O_3 molecule, the formal charge on the central O -atom is

In O3\mathrm{O}_3 molecule, the formal charge on the central O\mathrm{O}-atom isIn O_3 molecule, the formal charge on the central O -atom is

Options

  1. A00
  2. B−1-1
  3. C−2-2
  4. D+1+1

Correct answer

D. +1+1

Step-by-step solution

Lewis gave the structure of O3\mathrm{O}_3 molecule as In O_3 molecule, the formal charge on the central O -atom is
Using the relation, Formal charge =[=[ Total no. of valence electrons in the free atom] - [Total no. of non-bonding (lone pair) electrons] - 12\frac{1}{2} [Total no. of bonding (shared) electrons] The formal charge on central O\mathrm{O}-atom i.e., no. 1 =6−2−12(6)=+1=6-2-\frac{1}{2}(6)=+1
