| [A] Coloured ion | (P) \[C{{O}^{+}}\] |
| [B]\[\mu =1.73\,B.M\] | (Q) \[C{{O}^{2+}}\] |
| [C] \[{{d}^{10}}=~\]Configuration | (R) \[F{{e}^{2+}}\] |
| [D] More than 3 unpaired electrons | (S) \[M{{n}^{2+}}\] |
A) \[A\to R,P,Q;\text{ }B\to R,S;\text{ }C\to R;\text{ }D\to Q,S\]
B) \[A\to S,P;\text{ }B\to P;\,C\to R;D\to Q,S\]
C) \[A\to Q,R,S;\text{ }B\to Q;C\to P;\text{ }D\to R,S\]
D) \[A\to P,Q,S;\text{ }B\to Q;C\to P;\text{ }D\to R,S\]
Correct Answer: C
Solution :
[A] Coloured ion \[=C{{u}^{2+}},F{{e}^{2+}},M{{n}^{2+}}\] (Presence of unpaired \[{{e}^{\Theta }}\]) [B] \[\mu =1.73\,B.M=C{{u}^{2+}}\] ion having one unpaired \[{{e}^{\Theta }}\] [C] d10 = Cu" ion having 3d10 \[{{d}^{10}}=C{{u}^{+}}\] [D] More than 3 unpaired \[{{e}^{\Theta }}=F{{e}^{2+}}(4{{e}^{\Theta }}),M{{n}^{2+}}(4{{e}^{\Theta }})\]
