Question

The name of complex ion, `[Fe(CN_(6))]^(3-)` is
A. Tricyanoferrate (III) ion
B. Hexacyanidoferrate (III) ion
C. Hexacyanoiron (III) ion
D. Hexacyanitoferrate (III) ion

Answer 1

Correct Answer - B
The ligands are named before the name of the central atom/ion, Name of negatively charged (nionic) ligands bend in `-O` . If the complex ion is an anion, the name of the metal ends with the suffix - ate. Oxidation state of the metal in coordination entity is indicated by Roman numerals in Parenthesis. thus, the name of given complex ion is Hexacyanidoferrate (III) ion
