Question

The IUPAC name of ferric ferrocyanide is:

• A. hexacyanoferrate (II)
• B. iron (II) hexacyanoferrate (III)
• C. iron (III) hexacyanoferrate (II)
• D. iron (II) hexacyanoferrate (II)

Answer 1

Answer: (C)

iron (III) hexacyanoferrate (II)

The formula of ferric ferrocyanide is $F{e}_4\left[Fe\right(CN{)}_6{]}_3$.

so here the molecule contains $F{e}^{+3}$ and $\left[Fe\right(CN{)}_6{]}^{4-}$. negative ligand has IUPAC name hexacyanoferrate (II)

$F{e}^{+2}$- ferrate(ii) $F{e}^{+3}$-iron (iii) $C{N}^{-}$- cyano

So the IUPAC name is iron(iii )hexacyanoferrate (II)
