Which of the following coordination comp...

Which of the following coordination compounds exhibits ionisation isomerism
(a) `[Cr(NH_(3))_(6)]CI_(3)`
(b) `[Cr(en)_(3)CI_(3)]`
(c ) `[Cr(en)_(3)]CI_(3)`
(d) `[Co(NH_(3))_(5)Br]SO_(4)` .

Text Solution

Verified by Experts

The correct Answer is:
d
`[Cr(NH_(3))_(5)Br]SO_(4)` will give white ppt of `BaSO_(4)` with `BaCI_(2)` and `[Cr(NH_(3))_(5)SO_(4)]Br` will give yellow ppt of `AgBr` with `AgNO_(3)` and hence it gives ionisation isomers .
