Question

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

Options

• -1

• +2

• 0

• +1

Answer 1

In ozone molecule the formal charge on the central oxygen atom is +1.

Explanation:

The formal charge can be calculated using formula,

Formal charge = number of valence electrons - `1/2`
(number of electrons in bond pairs) - number of electrons in lone pair.

For O₃,

Formal charge for central atom O(1)

`= 6 - 2 - 1/2(6)`

= + 1
