Identify the homoleptic complexes with odd number of d electrons in the central metal :
(A) \(\left[\mathrm{FeO}_4\right]^{2-}\)
(B) \(\left[\mathrm{Fe}(\mathrm{CN})_6\right]^{3-}\)
(C) \(\left[\mathrm{Fe}(\mathrm{CN})_5 \mathrm{NO}\right]^{2-}\)
(D) \(\left[\mathrm{CoCl}_4\right]^{2-}\)
(E) \(\left[\mathrm{Co}\left(\mathrm{H}_2 \mathrm{O}\right)_3 \mathrm{~F}_3\right]\)
Choose the correct answer from the options given below :
- A (A), (B) and (D) only
- B (C) and (E) only
- C (B) and (D) only
- D (A), (C) and (E) only
Answer & Solution
Correct Answer
(C) (B) and (D) only
Step-by-step Solution
Detailed explanation
(A) \(\left[\mathrm{FeO}_4\right]^{2-} \Rightarrow \mathrm{Fe}^{6+}=3 \mathrm{~d}^2\) (B) \(\left[\mathrm{Fe}(\mathrm{CN})_8\right]^{3-} \Rightarrow \mathrm{Fe}^{3+}=3 \mathrm{~d}^5\) (C)…
