Which of the following pairs of complexes are isomerric with each other but their aqueous solution exhibit different molar conductivities?

Answer»

`[PtCl_(2)(NH_(3))_(4)]Br_(2) and [Pt Br_(2)(NH_(3))_(4)]Cl_(2)`<BR>`[CoCl_(2)(NH_(3))_(4)]NO_(2) and [CoCl(NO_(2))(NH_(3))_(4)]Cl`
`[Co(NO_(2))(NH_(3))_(5)]Cl_(2) and [Co(ONO)(NH_(3))_(5)]Cl_(2)`
`[CoBr(NH_(3))_(5)]SO_(4) and [Co(SO)_(4))(NH_(3))_(5)]Br`

Solution :`[CoBr(NH_(3))_(5)]SO_(4) hArr [CoBr(NH_(3))_(5)]^(2+)+SO_(4)^(2-), "Total CHARGES"=4`
`[Co(SO_(4))(NH_(3))_(5)Br hArr [Co(SO_(4))(NH_(3))_(5)]^(+)+Br^(-),"total charges"=2`
Hence, both have DIFFERENT molar CONDUCTIVITIES.
