What is the number of moles of donor atoms in n mole of \(\mathrm{NO}_2^{-}\)?
- A \(3 \mathrm{n}\)
- B \(0\)
- C \(2 \mathrm{n}\)
- D \(\mathrm{n}\)
Answer & Solution
Correct Answer
(C) \(2 \mathrm{n}\)
Step-by-step Solution
Detailed explanation
The ligand \(\mathrm{NO}_2^{-}\)links to metal ion through nitrogen or oxygen. Hence, there are two donor atoms per molecule and \(2 \mathrm{n}\) moles donor atoms per n mole.
