A) both have half-filled p and d-orbital
B) cuprous ion has completed d-orbital and cupric ion has incomplete d-orbital
C) cuprous ion has incomplete d-orbital and cupric ion has complete d-orbital
D) both have unpaired electrons in d-orbital
Correct Answer: B
Solution :
Cuprous ion has completed d-orbital\[(3{{d}^{10}})\] hence it is colourless, while cupric ion has incomplete d-orbital \[(3{{d}^{9}})\] and therefore, it is coloured. Cuprous ion\[(3{{d}^{10}}):\] Cupric ion \[(3{{d}^{9}}):\]You need to login to perform this action.
