Consider the following transformation : ...

Consider the following transformation :
`2CuX_(2) overset("Room temperature")(to) 2CuX+X_(2) (uarr)`
Then `X^(-)` can be:

A

`F^(-), Br^(-)`

B

`Cl^(-), Br^(-)`

C

`CN^(-), I^(-)`

D

`Cl^(-), F^(-)`

Text Solution

Verified by Experts

The correct Answer is:
C
`Cu(CN)_(2) and CuI_(2)` being unstable spontaneously decomposes into `CuCN(darr) and CuI(darr)` respectively at room temperature.
