A) \[A{{g}_{2}}S{{O}_{4}}\]
B) \[CuCl\]
C) \[Cu{{F}_{2}}\]
D) \[Mg{{F}_{2}}\]
Correct Answer: C
Solution :
\[Cu{{F}_{2}}\] is coloured due to incomplete d-subshell of valence shell in \[C{{u}^{++}}\] ion. \[C{{u}^{2+}}=1{{s}^{2}},2{{s}^{2}},2{{p}^{6}},3{{s}^{2}},3{{p}^{6}},3{{d}^{9}}\]You need to login to perform this action.
