A metal complex having composition [Cr(N...

A metal complex having composition `[Cr(NH_(3))_(4)Br_(2)I]` was isolated in two forms (X) and (Y). Form (X) reacts with `AgNO_(3)` to give a pale yellow precipitate which is partially soluble in excess of `NH_(4)OH` whereas (Y) gives a greenish yellow precipitate which is insoluble in `NH_(4)OH`.
what is formula of X and Y?

A

The formula of (X) and (Y) are `[Cr(NH_(3))_(4)BrI]Br" and "[Cr(NH_(3))_(3)Br_(2)I]NH_(3)` respectively

B

The formula of (X) and (Y) are `[Cr(NH_(3))_(4)BrI]Br" & "[Cr(NH_(3))_(4)Br_(2)]I` repectively

C

The formula of (X) and (Y) are both `[Cr(NH_(3))_(4)I]Br_(2)`

D

The formula of (X) and (Y) are `[Cr(NH_(3))_(2)IBr_(2)](NH_(3))_(2)`

Text Solution

Verified by Experts

The correct Answer is:
b
X has one `Br^(-)` ion outside the co-ordination sphere. Y has `I^(-)` outside the co-ordination sphere. Note AgBr is partially soluble in ammonia whereas AgI is insoluble.
