Question

In $N{a}_2\left[Fe\right(CN{)}_{5}NO]$ sodium nitroprusside ___________.

• A. Oxidation state of Fe is +2
• B. This has $N{O}^{+}$ as ligand
• C. It is paramagnetic
• D. None is correct

Answer 1

Answer: (A), (B)

The correct options are
A Oxidation state of Fe is +2
B This has $N{O}^{+}$ as ligand

Option (A),(B) is correct.
In $N{a}_2\left[Fe\right(CN{)}_{5}NO]$,oxidation state of Fe is +2 and has $N{O}^{+}$ as ligand. It is dimagnetic as $d^6$ electrons are paired up due to the influence of $CN$ and $NO$ ligands.
