Question
What is the correct IUPAC name for Ir(NO₂)₄
Answer
iridium(IV) nitrate
- Identify the element symbol for Ir. A:Ir stands for Iridium.
- Identify the ligand symbol for NO₂. A: NO₂ stands for nitro.
- Determine the oxidation state of Iridium. A:Since there are four NO₂ groups, each with a charge of -1, the total charge contributed by these ligands is -4, Therefore, the oxidation state of Ir must be +4 to balance this charge.
- Write the name of the ligand following the metal and add the oxidation state, in Roman numerals, within parentheses. A:The name of the compound is iridium(IV) nitrate.
