Question
Cumbrous ion is collarless while cupric ion is colored because
Options
A.Both have half filled p-and d-orbitals
B.Cumbrous ion has incomplete d-orbital and cupric ion has a complete d-orbital
C.Both have underpaid electrons in the d-orbitals
D.Cumbrous ion has complete d-orbital and cupric ion has a incomplete d-orbital
Solution
In Cu+[Ar]3d10 there is no unpaired electron, Cu2+[Ar]3d9 contains one paired, electron hence colored.
