In coordination chemistry there are a veriety of methods applied to find out the structure of complexes. One method involves treating the complex with known reagents and from the nature of reaction, the formula0 of the complex can be predicted. An isomers of the complex `Co(en)_(2)(H_(2)O)Cl_(2)Br`, on reaction with concentrated `H_(2)SO_(4)` (dehydrating agent ) it suffers loss in weight and on reaction with `AgNO_(3)` solution it gives a white precipitate which is soluble in `NH_(3)(aq)`.
The correct formula of the complex is :

A

`[CoCIBr(en)_(2)]H_(2)O`

B

`[CoCl(en)_(2)(H_(2)O)]BrCl`

C

`[CoBr(en)_(2)(H_(2)O)]Cl_(2)`

D

`[CoBrCl(en)_(2)]Cl.H_(2)O`

Text Solution

Verified by Experts

(D), As it suffer loss in weight with `H_(2)SO_(4)` . Ionization sphere contains `H_(2)O` molecules . As complex also give white ppt. with `AgNO_(3)` , the isnization sphere should contain `Cl^(-)` ion. So formula may be `[CoBrCl(en)_(2)]Cl.H_(2)O`.
