A) \[S{{c}^{3+}}\]
B) \[F{{e}^{2+}}\]
C) \[T{{i}^{3+}}\]
D) \[M{{n}^{2+}}\]
Correct Answer: A
Solution :
\[{{\operatorname{Sc}}^{3+}}\to \,\,3{{d}^{6}}\,4{{s}^{0}}\] \[{{\operatorname{Fe}}^{2+}}\to 3{{d}^{6}}\,4{{s}^{0}}\] \[{{\operatorname{Ti}}^{3+}}\to \,3{{d}^{1}}\,4{{s}^{0}}\] \[M{{n}^{2+}}\to 3{{d}^{5}}\,4{{s}^{0}}\] In \[S{{c}^{3+}}\] there is/are no unpaired electrons. So the aqueous solution of \[S{{c}^{3+}}\] will be colourless.You need to login to perform this action.
