the the formal charges of oxygen labelled 321 in oxygen respectively are
Answers
Answer : The formal charge of each oxygen atom in ozone O_1,O_2\text{ and }O_3 are 0, +1 and -1 respectively.
Explanation :
First we have to draw Lewis-dot structure of ozone, O_3.
Oxygen has '6' valence electrons.
Therefore, the total number of valence electrons in ozone, O_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}
\text{Formal charge on }O_1=6-4-\frac{4}{2}=0
\text{Formal charge on }O_2=6-2-\frac{6}{2}=+1
\text{Formal charge on }O_1=6-6-\frac{2}{2}=-1
The Lewis-dot structure are shown below.
