A)
B)
C)
D)
Correct Answer: D
Solution :
Formal charges help in the selection of the lowest energy structure from a number of possible Lewis structures for a given species. |
Generally the lowest energy structure is the one with the smallest formal charges on the atoms. |
Formal charge on an atom: |
= total no. of valence electrons-non-bonding electrons \[-\frac{1}{2}\times \] bonding electrons. |
For Lewis structure of \[S{{O}_{3}}\] |
Formal charge on S atom \[=6-0-\frac{1}{2}\times 12=0\] |
Formal charge on three O atoms |
\[=6-4-\frac{1}{2}\times 4=0\] |
