An isomerr of the complex CoBrCl_(2)(en)_(2)(H_(2)O), on reaction with concentrated H_(2)SO_(4) (dehydrating agent), suffers no loss in weight and on reaction with AgNO_(3) solution it gives only white precipitate, which is soluble in NH_(3) solution. Q. The correct formula of the complex is:

Answer»

`[CoBrH_(2)O(en)_(2)]Cl_(2)`
`[COCL(en)_(2)H_(2)O]BrCl`
`[CoBrCl(en)_(2)]CL*H_(2)O`
`[CoCl_(2)(en)_(2)]Br*H_(2)O`

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