• The compound (c) Na2[CdCl4] is not coloured.
• due to the presence of Cd central atom.
• Cd has d10 electronic configuration, so that transition does not occur.

Na₂[CdCl₄ ] is the non coloured complex.
Explanation:
- Colour of a transition element comes form the p to d transition or d to d transition of the electrons.
- Because of the less energy difference of the 5s and 4d electrons, they can be transited from one shell to other.
- In case of cadmium, the atomic number of cadmium is 48.
- The end electronic configuration of cadmium is 4d10 5s2.
- Now with Cd2+, the end electronic configuration is 4d10.
- So there's no vacant d orbital for d d transition.
- So there's no colour to this compound.
