Q. In ozone molecule the formal charge on the central oxygen atom is

MHT CETMHT CET 2019Chemical Bonding and Molecular Structure

Solution:

Key Idea The formal charge can be calculated using formula,

Formal charge = number of valence electrons $-\frac{1}{2}$

(number of electrons in bond pairs) - number of electrons in lone pair

Formal charge for central atom $O (1)$

$=6-2-\frac{1}{2}(6)=+1$
