MCQ
The color of Cu+ compounds is?
- AWhite
- BBlue
- COrange
- DYellow
✓
Answer
- White
Explanation:
Cu+ compounds are generally colourless (white). The electronic configuration is 3d104s0. So there is no unpaired electron present in the ion. So the electronic transition between two energy levels t2g and eg (responsible for the colour of transition metals) is not possible.
