MP Board Class 12 Chemistry — The IUPAC name of the coordi

Q: The IUPAC name of the coordination compound K3Fe(C2O4)3 is:

To name K3Fe(C2O4)3: 1. Name the cation first: Potassium. 2. Name the ligands alphabetically: tris(oxalato). 3. Name the central metal atom with its oxidation state in Roman numerals in brackets. Since the complex is an anion (Fe(C2O4)33-), the iron is named ferrate, and its oxidation state is +3 (calculated as +3 + x + 3(-2) = 0 => x = +3). Thus, the IUPAC name is Potassium trioxalatoferrate(III).

Step-by-Step Solution

To name K3[Fe(C2O4)3]: 1. Name the cation first: Potassium. 2. Name the ligands alphabetically: tris(oxalato). 3. Name the central metal atom with its oxidation state in Roman numerals in brackets. Since the complex is an anion ([Fe(C2O4)3]3-), the iron is named ferrate, and its oxidation state is +3 (calculated as +3 + x + 3(-2) = 0 => x = +3). Thus, the IUPAC name is Potassium trioxalatoferrate(III).
