Vedclass · Answer

(D) The formula for formal charge is: $	ext{Formal charge} = (	ext{Valence electrons}) - (	ext{Non-bonding electrons}) - \frac{1}{2}(	ext{Bonding electrons})$.For oxygen atom $2$ (terminal oxygen with double bond): Valence electrons = $6$,Non-bonding electrons = $4$,Bonding electrons = $4$. Formal charge = $6 - 4 - \frac{1}{2}(4) = 6 - 4 - 2 = 0$.For oxygen atom $1$ (central oxygen): Valence electrons = $6$,Non-bonding electrons = $2$,Bonding electrons = $6$. Formal charge = $6 - 2 - \frac{1}{2}(6) = 6 - 2 - 3 = +1$.For oxygen atom $3$ (terminal oxygen with single bond): Valence electrons = $6$,Non-bonding electrons = $6$,Bonding electrons = $2$. Formal charge = $6 - 6 - \frac{1}{2}(2) = 6 - 6 - 1 = -1$.Thus,the formal charges on oxygen atoms $2, 1$ and $3$ are $0, +1$ and $-1$ respectively.

The correct formal charges on oxygen atoms numbered $2$,$1$ and $3$ respectively are:
