Why are copper(I) compounds colorless although copper is a … – Quora
Compounds of copper(I) are colourless, because copper(I) has electronic configuration with 3d^10 i.e with completely filled 3d-sublevel of electrons. So, no possibility d-d transition in the visible region. It seems also these copper(I) compound lack charge transfer spectra in the visible region because Cu(I) is not highly charged and has relatively large radius i.e the ratio charge/radius is not enough to polarize ligand. Also, these Cu(I) compounds are stoichiometric.

Cuprous ion is colourless while cupric ion is coloured because – Toppr Ask
Cupric ion (Cu+2)has electronic configuration [Ar]3d94s0so it has an unpaired electron. So it can undergoes d-d transition. So, the cuprous ion has the complete d-orbitals while the cupric ion has incomplete d-orbitals. Hence, the cuprous ion is colourless and the cupric ion has a colour. Final Answer:The correct answer is A.

Explain why the compounds of copper (II) are coloured, but those of …
The presence of one unpaired electron in 3d-orbital results in d-d transition due to which, Cu2+ ions absorb red light from visible spectrum and emit blue light. Therefore, copper (II) compounds are coloured. iii. In case of zinc, the electronic configuration is Zn: [Ar] 3d104s2 and Zn2+: [Ar] 3d10. iv.

Scandium(III) complexes are colourless because no visible light is absorbed. In the zinc case, the 3d level is completely full – there aren’t any gaps to promote an electron in to. Zinc complexes are also colourless. Tetrahedral complexes. Simple tetrahedral complexes have four ligands arranged around the central metal ion. Again the ligands have an effect on the energy of the d electrons in the metal ion. This time, of course, the ligands are arranged differently in space relative to the …

No visible light is absorbed, so the eye sees no change, and the compound appears white or colorless. A solution containing [Cu (CN) 2] −, for example, is colorless. On the other hand, octahedral Cu 2+ complexes have a vacancy in the eg orbitals, and electrons can be excited to this level.
