Question
The compound which is not coloured is
Options
A.K4Fe(CN)6
B.K3Fe(CN)6
C.Na2CdCl4
D.Na2CuCl4
Solution
In Na2CdCl4, Cd has oxidation state + 2, so its electronic configuration is 4d10 4s10. or all the 4 d orbitals are fully filled.
Hence, there will not be d-d transition resulting in colour. So,it is colourless.
