What is the formal charge on carbon atom in \(\mathrm{CO}_3^{2-}\) ion?
- A -2
- B -4
- C 4
- D zero
Answer & Solution
Correct Answer
(D) zero
Step-by-step Solution
Detailed explanation
Formal charg \(e=\left[\begin{array}{c}\text { Total no.of valence } \\ e ^{-} \text {in freestate }\end{array}\right]\) \(-\left[\begin{array}{c}\text { Total no.oflone } \\ \text { pair electrons }\end{array}\right]\) \(-\frac{1}{2}\left[\begin{array}{c}\text { no.of bonding electrons } \\ \text { on that particular atom }\end{array}\right]\)
\(=4-0-\frac{1}{2} \times 8=0\)
