IUPAC Naming of Coordination Compounds

What is the IUPAC name for [Cu(NH3)4]SO4?

• copper(II) sulfate tetraamine

• tetraamminecopper(II) sulfate

• copper(II) ammonium sulfate

• tetraaminecopper(I) sulfate

How do you name a complex with a bidentate ligand?

• [Ligand name] [oxidation state] [metal name]

• [Metal name] [ligand name] (charge)

• [Metal name] (oxidation state) [ligand name]

• [Ligand name] [metal name] (oxidation state)

What is the correct IUPAC name for [Fe(CN)6]3-?

• dicyanoferrate(II)

• hexacyanoferrate(III)

Explain the significance of oxidation state in naming complexes.

• The oxidation state is significant in naming complexes as it indicates the charge of the metal, differentiating between complexes with similar ligands.

• Oxidation state only affects the color of the complex.

• The oxidation state is only important for organic compounds.

• The oxidation state is irrelevant in naming complexes.

What is the IUPAC name for [CoCl2(en)2]?

• bis(ethylenediamine) dichlorocobalt(II)

• ethylenediamine dichlorocobalt(II)

• dichloroethylenediamine cobalt(II)

• bis(ethylenediamine) dichlorocobalt(III)

How do you determine the coordination number of a complex?

• The coordination number is the total number of protons in the central metal ion.

• The coordination number is the total number of ligand atoms bonded to the central metal ion.

• The coordination number is the number of electrons in the outer shell of the metal ion.

• The coordination number is determined by the size of the ligands used in the complex.

What is the IUPAC name for [Ni(H2O)6]Cl2?

• nickel(II) chloride

• hexahydronickel(II) chloride

• dihydroxynickel(II) chloride

• hexaaquanickel(II) chloride

What is the role of ligands in the naming of coordination compounds?

• Ligands determine the prefixes for quantity and the order in naming coordination compounds.

• Ligands only affect the color of coordination compounds.

• Ligands are irrelevant in the naming process of coordination compounds.

• Ligands determine the chemical stability but not the naming order.

How do you name a complex with a bridging ligand?

• Name the bridging ligand first, followed by the metal centers.

• Name the metal centers first, followed by the bridging ligand.

• Only name the bridging ligand without mentioning the metal centers.

• List the bridging ligand and metal centers in any order.

What is the IUPAC name for [Ag(NH3)2]NO3?

• diammine silver(I) nitrate
