Question

Calcule the formula charge of each oxygen atom of ozone molecule​

Answer 1

Answer:

The formal charge of each oxygen atom in ozone O_1,O_2\text{ and }O_3O

1

,O

2

and O

3

are 0, +1 and -1 respectively.

Explanation :

First we have to draw Lewis-dot structure of ozone, O_3O

3

.

Oxygen has '6' valence electrons.

Therefore, the total number of valence electrons in ozone, O_3O

3

= 3(6) = 18

According to electron-dot structure, there are 12 number of bonding electrons and 6 number of non-bonding electrons.

Now we have to calculate the formal charges of each oxygen atom.

Formula for formal charge :

\text{Formal charge}=\text{Valence electrons}-\text{Non-bonding electrons}-\frac{\text{Bonding electrons}}{2}Formal charge=Valence electrons−Non-bonding electrons−

=0

\text{Formal charge on }O_2=6-2-\frac{6}{2}=+1Formal charge on O

=+1

\text{Formal charge on }O_1=6-6-\frac{2}{2}=-1Formal charge on O
