A) Cu (II) is more stable
B) Cu (II) is less stable
C) Cu (I) and Cu (II) are equally stable
D) Stability of Cu (I) and Cu (II) depends on the nature of Cu salts
Correct Answer: A
Solution :
Though Cu (I) has \[3{{d}^{10}}\]configuration (stable) while Cu (II) has \[3{{d}^{9}}\]configuration, yet Cu (II) is more stable due to greater effective nuclear charge of Cu (II) (i.e., to hold 17 electrons instead of 18 in Cu(l)).You need to login to perform this action.
