  • What is the general order for naming coordination compounds?
    The metal cation is written before the nonmetal anion, and the complex ion is named before the counter ion.
  • When do you use Roman numerals in naming coordination compounds?
    Roman numerals are used for transition metals with more than one possible charge, except for zinc (+2), cadmium (+2), and silver (+1), which do not require them.
  • How are neutral and anionic ligands ordered when naming a complex ion?
    Neutral ligands are named before anionic ligands within the complex ion.
  • How are ligands listed within the name of a complex ion?
    Ligands are named in alphabetical order, ignoring numerical prefixes like di-, tri-, etc.
  • What suffix is added to anionic ligands when naming coordination compounds?
    The 'ide' ending is dropped and replaced with 'o' (e.g., chloride becomes chloro).
  • How is water named as a ligand in coordination compounds?
    Water is named 'aqua' when it acts as a ligand.
  • What is the ligand name for NH3 in coordination compounds?
    NH3 is named 'ammine' as a ligand.
  • What is the ligand name for CO in coordination compounds?
    CO is named 'carbonyl' as a ligand.
  • How do you indicate the number of each ligand in a complex ion?
    Numerical prefixes such as di-, tri-, tetra-, penta-, and hexa- are used to show the number of each ligand.
  • What change is made to the metal name if the complex ion is an anion?
    The metal name is modified to its Latin root and the suffix '-ate' is added (e.g., iron becomes ferrate).
  • How is the charge of the central metal ion determined in a complex?
    The charge is calculated by considering the charges of the ligands and counter ions, treating it like a math problem to solve for the metal's charge.
  • Where are brackets used in the formula of coordination compounds?
    Brackets are used to enclose the entire complex ion in the formula.
  • How is a counter ion named if it is a nonmetal?
    The counter ion is named with the suffix '-ide' (e.g., bromide for Br-).
  • What is the only place a space should appear in the name of a coordination compound?
    A space appears only between the cation and the anion portions of the compound's name.
  • Why is it important to know the rules for naming coordination compounds?
    Knowing the rules is essential because you may be asked to name a compound from its formula or write the formula from its name.
