Coordination Chemistry - SS2 Chemistry Past Questions and Answers - page 1
Coordination compounds are formed by the coordination of a central metal atom or ion with:
Water molecules
Organic compounds
Ligands
Alkali metals
In coordination compounds, ligands coordinate to the central metal atom/ion through:
Ionic bonding
Covalent bonding
Hydrogen bonding
Metallic bonding
The coordination number of a metal in a coordination compound represents:
The number of ligands coordinated to the metal
The number of metal atoms present in the compound
The number of unpaired electrons on the metal
The charge of the metal ion
The name of a coordination compound is written by:
Starting with the name of the ligands and then the name of the central metal atom/ion
Starting with the name of the central metal atom/ion and then the name of the ligands
Only using the chemical formula of the compound
Writing the names of ligands and metal atom/ion in any order
The complex ion [Co(NH3)6]3+ has a coordination number of:
3
4
5
6
Ligands that can donate one electron pair to form a coordination bond are called:
Monodentate ligands
Bidentate ligands
Polydentate ligands
Chelating ligands
The coordination compound [Fe(CN)6]4- has a charge of:
+1
-1
+2
-2
A complex ion that contains both positive and negative charges is called:
Cationic complex
Anionic complex
Neutral complex
Chelating complex
The coordination isomerism in coordination compounds refers to:
Isomers with different coordination numbers
Isomers with different ligands but the same central metal atom/ion
Isomers with different ligands and different central metal atom/ion
Isomers with different oxidation states of the central metal atom/ion
The bonding between the ligands and the central metal atom/ion in coordination compounds is primarily due to:
Ionic bonding
Metallic bonding
Covalent bonding
