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. both(a) and (b) correct
• D. none of the above is correct

Answer 1

The correct option is C both(a) and (b) correct

In sodium nitroprusside $N{a}_2\left[Fe\right(CN{)}_{5}NO]$, Fe has oxidation state of +2 and $N{O}^{+}$ acts as ligand.
$NO\to N{O}^{+}+e^{-}$
$F{e}^{3+}+e^{-}\to F{e}^{2+}$
