(a)
Interpretation:
Systematic (IUPAC) name should be identified given the coordination compound.
Concept introduction:
Coordination compounds
- Coordination compound typically consists a complex ion and a counter ion.
- A complex ion contains a central meatal cation bonded to one or more molecules or ions.
- The molecules or ions that surrounded the metal in a complex ion are called ligands.
- A ligand has at least one unpaired of valance electrons.
IUPAC naming method: There are some rules set by the IUPAC, the ligand names is first followed by metal name.
Charge of metal indicated with roman numerical and closed in parenthesis after name all in one “word”.
Ligand listed alphabetically, ignoring prefixes that denote the number of each type of ligand. Cations are named before anions.
For anionic ligands end in
For neutral ligands, the common name of the molecule is used e.g.
For example:
