Given: Complex compound of Co3 with molecular formula CoClxyNH gives a total of three ions per molecule when dissolved in water.
To determine: How many Cl ions satisfy primary as well secondary valencies in this complex?
Solution:
- The molecular formula of the complex compound is CoClxyNH.
- The compound gives a total of three ions per molecule when dissolved in water, which means that it is a cationic complex with a charge of +3.
- The coordination number of cobalt in the complex is 6, as it is a transition metal and can form 6 coordination bonds.
- The NH ligand is neutral and does not contribute any charge to the complex.
- Therefore, the charge on the complex is +3, and the sum of the charges of the ligands must be -3 to balance the charge on the complex.
- The Cl ions have a charge of -1 each, so the number of Cl ions in the complex is equal to the absolute value of the charge on the complex, which is 3.
- The Cl ions can satisfy either primary or secondary valencies in the complex.
- Primary valencies are satisfied by the ligands directly attached to the metal ion, while secondary valencies are satisfied by the ligands that are not directly attached to the metal ion but are still part of the coordination sphere.
- Since the coordination number of cobalt in the complex is 6, all 6 coordination sites are occupied by either Cl or NH ligands.
- Therefore, all the Cl ions in the complex satisfy primary valencies and none of them satisfy secondary valencies.
- Hence, the number of Cl ions that satisfy both primary and secondary valencies in this complex is 0.
- The correct option is (c) 1.
Therefore, the answer is option 'C', 1 Cl ion satisfies either primary or secondary valency.
To determine: How many Cl ions satisfy primary as well secondary valencies in this complex?
Solution:
- The molecular formula of the complex compound is CoClxyNH.
- The compound gives a total of three ions per molecule when dissolved in water, which means that it is a cationic complex with a charge of +3.
- The coordination number of cobalt in the complex is 6, as it is a transition metal and can form 6 coordination bonds.
- The NH ligand is neutral and does not contribute any charge to the complex.
- Therefore, the charge on the complex is +3, and the sum of the charges of the ligands must be -3 to balance the charge on the complex.
- The Cl ions have a charge of -1 each, so the number of Cl ions in the complex is equal to the absolute value of the charge on the complex, which is 3.
- The Cl ions can satisfy either primary or secondary valencies in the complex.
- Primary valencies are satisfied by the ligands directly attached to the metal ion, while secondary valencies are satisfied by the ligands that are not directly attached to the metal ion but are still part of the coordination sphere.
- Since the coordination number of cobalt in the complex is 6, all 6 coordination sites are occupied by either Cl or NH ligands.
- Therefore, all the Cl ions in the complex satisfy primary valencies and none of them satisfy secondary valencies.
- Hence, the number of Cl ions that satisfy both primary and secondary valencies in this complex is 0.
- The correct option is (c) 1.
Therefore, the answer is option 'C', 1 Cl ion satisfies either primary or secondary valency.

The compound is [Co(NH3)5Cl]Cl2 so the number of Cl- atoms that satisfy primary as well as secondary valency is 1 i.e. inside coordination sphere
