What is the IUPAC name for potassium hexacyanidoferrate(III), ?
Answer and explanation
Correct answer: C. Potassium hexacyanidoferrate(III)
- Step 1: Determine oxidation state of iron: .
- Step 2: For anionic complexes, the metal name takes the Latin root ending with '-ate': ferrate(III).
- Step 3: Combining the cation and complex anion names: potassium hexacyanidoferrate(III).
Answer
Potassium hexacyanidoferrate(III).
Why not the others: Tripotassium hexacyanoiron(III) incorrectly uses stoichiometric prefix 'tri' for counter-ion and 'iron' instead of 'ferrate'; Potassium hexacyanidoiron(II) has incorrect oxidation state and English metal name; Potassium cyanoferrate(III) omits the numerical prefix 'hexa'.
