  • What is the correct IUPAC name for the ion with the formula [PtBr6]4-?
    The ion [PtBr6]4- is named hexabromoplatinate(IV). The six bromide ligands are named 'hexabromo', and since the complex ion is an anion, the metal name 'platinum' is changed to 'platinate'. The oxidation state of platinum is IV, indicated in parentheses.
  • What is the rule for naming ligands inside a coordination complex with respect to alphabetical order?
    Ligands inside a coordination complex are named in alphabetical order, ignoring any numerical prefixes like di-, tri-, or tetra-.
  • How are neutral and anionic ligands ordered when naming a coordination complex?
    Neutral ligands are listed before anionic ligands when naming a coordination complex.
  • What suffix is added to the name of a metal when the complex ion is an anion?
    The suffix '-ate' is added to the metal's name when the complex ion is an anion.
  • How do you determine the oxidation state of the central metal in a coordination complex?
    The oxidation state is determined by treating the charges of the ligands and counterions as a math problem and solving for the metal's charge.
  • What is the naming convention for halide ligands inside a coordination complex?
    Halide ligands inside a complex are named by dropping the '-ide' ending and adding '-o' (e.g., 'bromo' for Br-).
  • When is a Roman numeral used in the name of a coordination compound's metal?
    A Roman numeral is used if the metal can have more than one possible oxidation state, except for metals like zinc, cadmium, and silver, which have fixed charges.
  • What is the correct name for the ligand NH3 in a coordination complex?
    NH3 is named 'ammine' when it acts as a ligand in a coordination complex.
  • How is the counterion outside the brackets named in a coordination compound?
    The counterion outside the brackets is named as a regular ion, using its standard ionic name (e.g., 'bromide' for Br-).
  • What is the significance of brackets in the formula of a coordination complex?
    Brackets are used to enclose the entire complex ion, distinguishing it from any counterions present.
