Question

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

• A. Oxidation state of $Fe$ is $+2$
• B. This has $N{O}^{+}$as ligand
• C. Both(a) and (b)
• D. None of the above is correct

Answer 1

Answer: (C)

$NO\to N{O}^{+}+e^{-}$
$F{e}^{3+}+e^{-}\to F{e}^{2+}$
Oxidation state of $Fe$ is $+2$ and $N{O}^{+}$is ligand
