Exploring Coordination Compounds

What are the nomenclature rules for naming anionic ligands?

• Anionic ligands are named by modifying the neutral molecule name, using '-o' endings, and applying prefixes for quantity.

• Anionic ligands are named by adding '-ate' to the neutral molecule name.

• Anionic ligands retain the neutral name without modification.

• Anionic ligands are named using '-ic' endings and no prefixes.

How do you name a complex ion with a neutral ligand?

• Combine the metal and ligand names into one word.

• Name the metal ion followed by the neutral ligand.

• Use the ligand name first, then the oxidation state of the metal.

• Name the neutral ligand followed by the metal ion.

What is the oxidation state of the central metal in [Cu(NH3)4]2+?

• +3

• +1

• 0

What does the coordination number indicate in a complex?

• The spatial arrangement of ligands around the metal ion.

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

• The charge of the central metal ion.

• The total number of metal ions in the complex.

Explain the significance of isomerism in coordination compounds.

• All coordination compounds are identical regardless of isomerism.

• Isomerism in coordination compounds is significant as it results in different properties and behaviors, impacting their applications in various fields.

• Isomerism has no effect on the properties of coordination compounds.

• Isomerism only affects the color of coordination compounds.

Describe the difference between geometric and optical isomerism in coordination compounds.

• Geometric isomerism refers to the rotation of bonds, while optical isomerism deals with the color of compounds.

• Geometric isomerism involves different spatial arrangements (e.g., cis/trans), while optical isomerism involves non-superimposable mirror images (enantiomers).

• Geometric isomerism is only found in organic compounds, while optical isomerism is exclusive to inorganic compounds.

• Geometric isomerism involves only linear arrangements, while optical isomerism involves superimposable images.
