The formal charges of \(\mathrm{C}\) and \(\mathrm{O}\) atoms in \(\mathrm{CO}_2(\ddot{O}=\mathrm{C}=\ddot{\mathrm{O}}\) :) are, respectively
- A \(1,-1\)
- B \(-1,1\)
- C \(2,-2\)
- D 0,0
Answer & Solution
Correct Answer
(D) 0,0
Step-by-step Solution
Detailed explanation
Formal charge \((\mathrm{FC})=\left[V-l p-\frac{1}{2} b p\right]\) [where, \(V=\) valence electrons, \(l p=\) lone pair and \(b p=\) bond pair] For O=C=[18O] \(\mathrm{FC}\) of \(\mathrm{O}=6-4-\frac{1}{2} \times 4=0\) \(\mathrm{FC}\) of \(\mathrm{C}=4-0-\frac{1}{2} \times 8=0\)
