Coordination compounds

What does the primary valency of a coordination compound represent?

• The number of ligands attached to the central metal atom

• The oxidation state of the central metal atom

• The total number of coordination sites available

• The geometric arrangement of ligands around the metal

Which of the following ligands is considered an ionisable ligand?

• Ammonia

• Water

• Chloride ion

• Ethylene diamine

In Werner's theory, what is the secondary valency of a coordination compound?

• The number of ionisable ligands

• The number of non-ionisable ligands

• The total number of bonds formed by the central metal atom

• The coordination number of the metal ion

Which of the following statements is true regarding non-ionisable ligands?

• They can dissociate in solution to form ions

• They do not contribute to the primary valency

• They are always neutral molecules.

• They can only form bidentate complexes
