Which of the following compound is not coloured ?

A

`Na_(2)[CuCl_(4)]`

B

`Na_(2)[CdCl_(4)]`

C

`K_(4)[Fe(CN)_(6)]`

D

`K_(3)[Fe(CN)_(6)]`

Text Solution

Verified by Experts

The correct Answer is:
A
`Na_(2)[CuCl_(4)]`
Oxidation state of copper =+2
Electronic configuration of `Cu^(2+)implies 3d^(9)`
As there is no d-d transition possible, the molecule is not coloured.
