What is the number of moles of donor atoms in n mole of NO ₂⁻ ?

Options

  1. A3 n
  2. B0
  3. C2 n
  4. Dn

Correct answer

C. 2 n

Step-by-step solution

The ligand NO ₂⁻ links to metal ion through nitrogen or oxygen. Hence, there are two donor atoms per molecule and 2 n moles donor atoms per n mole.
