In coordination chemistry there are a variety of methods applied to find out the structures of complexes. One method involves treating the complex with known reagents and from the nature of reaction, the formula of the complex can be predicted. An isomer of the complex Co(en)2(H2O)Cl2B4, on reaction with concentrated H2SO4 (dehydrating agent) it suffers loss in weight and on reaction with AgNO3 solution it gives a white precipitate which is soluble in NH3(aq).
Q.
The correct formula of the complex is :
- a)[CoClBr(en)2] H2O
- b)[CoCl(en) 2 (H2O)] BrCl
- c)[CoBr(en) 2 (H2O)] Cl2
- d)[CoBrCl(en) 2]Cl. H2O
Correct answer is option 'D'. Can you explain this answer?

As it suffer lose in weight with H2SO4, ionization sphere spther3e contains H2O molecle.
As complex also give white ppt. with AgNO3, the ionisation sphere should contain CI– ion.
So formula may be [CoBrCI(en)2]CI.H2O.
As complex also give white ppt. with AgNO3, the ionisation sphere should contain CI– ion.
So formula may be [CoBrCI(en)2]CI.H2O.

Given Information:
- Complex: Co(en)2(H2O)Cl2B4
- Reaction with H2SO4: Loss in weight
- Reaction with AgNO3: White precipitate soluble in NH3(aq)
Explanation:
To determine the correct formula of the complex, we need to analyze the given information and understand the reactions involved.
Reaction with H2SO4:
- Concentrated H2SO4 is a dehydrating agent, which means it removes water molecules from the complex.
- Loss in weight indicates the removal of water molecules from the complex.
- From the given complex formula, Co(en)2(H2O)Cl2B4, there is only one water molecule present.
- Therefore, the complex must lose this water molecule upon reaction with H2SO4.
Reaction with AgNO3:
- AgNO3 solution is added to the complex.
- A white precipitate is formed, which indicates the formation of AgCl.
- AgCl is insoluble in water, but soluble in NH3(aq) (ammonia solution).
- This indicates the presence of chloride ions (Cl-) in the complex.
Determining the Correct Formula:
- Based on the reactions, we can conclude that the complex loses one water molecule and contains chloride ions.
- The formula options that meet these criteria are:
a) [CoClBr(en)2] H2O
b) [CoCl(en)2(H2O)] BrCl
c) [CoBr(en)2(H2O)] Cl2
d) [CoBrCl(en)2]Cl. H2O
Eliminating the Incorrect Options:
- Option a) contains both chloride and bromide ions, but the reaction with AgNO3 only forms AgCl, indicating the absence of bromide ions. Therefore, option a) is incorrect.
- Option b) contains chloride ions, but the reaction with H2SO4 does not remove any water molecules. Therefore, option b) is incorrect.
- Option c) contains bromide ions, but the reaction with AgNO3 only forms AgCl, indicating the absence of bromide ions. Therefore, option c) is incorrect.
Conclusion:
- The correct formula of the complex is [CoBrCl(en)2]Cl. H2O, which is option d).
Note: It is important to carefully analyze the reactions and compare them with the given options to determine the correct formula of the complex.
