`Cu^(2+)(aq.)+X^(-)(aq.)overset(R.T.)toCuX darr+X_(2)`
'X' cannot be:

A

`Cl^(-)(aq.)`

B

`I^(-)(aq.)`

C

`CN^(-)(aq.)`

D

`SCN^(-)(aq.)`

Text Solution

Verified by Experts

The correct Answer is:
A
`Cu^(2+)(aq.)` has oxidizing property it oxidizes `I^(-)(aq.)CN^(-)(aq.)SCN^(-)(aq.)` into `I_(2),(CN)_(2),(SCN)_(2)` respectively but does not oxidize `Cl^(-)(aq.)` as it is weakerr reductant.
