Compounds with spin-only magnetic moment equivalent to five unpaired electrons are
- A \(\mathrm{K}_{4}\left[\mathrm{Mn}(\mathrm{CN})_{6}\right]\)
- B \(\left[\mathrm{Fe}\left(\mathrm{H}_{2} \mathrm{O}\right)_{6}\right] \mathrm{Cl}_{3}\)
- C \(\mathrm{K}_{3}\left[\mathrm{FeF}_{6}\right]\)
- D \(\mathrm{K}_{4}\left[\mathrm{MnF}_{6}\right]\)
Answer & Solution
Correct Answer
(D) \(\mathrm{K}_{4}\left[\mathrm{MnF}_{6}\right]\)
Step-by-step Solution
Detailed explanation
Among the given species \(\mathrm{H}_{2} \mathrm{O}\) and \(\mathrm{F}\) are weak field ligands and do not cause pairing of electrons in the central metal atom. As CN is a strong field ligand, it causes pairing of electrons in the central metal atom. Now, Oxidation state of :…
