The coordination number and oxidation state of \(\mathrm{Cr}\) in \(\mathrm{K}_3\left[\mathrm{Cr}\left(\mathrm{C}_2 \mathrm{O}_4\right)_3\right]\) are respectively
- A 3 and 3
- B 3 and 0
- C 6 and 3
- D 4 and 2
Answer & Solution
Correct Answer
(C) 6 and 3
Step-by-step Solution
Detailed explanation
Coordination number is also called ligancy of central atom in a molecule. It can be equal to the number of bonds formed by the ligand(s) with the central atom. \(\because\) In \(\mathrm{C}_2 \mathrm{O}_4^{2-}\), it bears \((-2)\) charge and form total 6 bonds with the central…
