In O ₃ molecule, the formal charge on the central O -atom is

Step-by-step solution

Lewis gave the structure of O ₃ molecule as Using the relation, Formal charge =[ Total no. of valence electrons in the free atom] - [Total no. of non-bonding (lone pair) electrons] - 1 2 [Total no. of bonding (shared) electrons] The formal charge on central O -atom i.e., no. 1 =6-2- 1 2 (6)=+1
