A) \[M{{n}^{2+}}>{{V}^{2+}}>C{{r}^{2+}}\]
B) \[{{V}^{2+}}>C{{r}^{2+}}>M{{n}^{2+}}\]
C) \[M{{n}^{2+}}>C{{r}^{2+}}>{{V}^{2+}}\]
D) \[C{{r}^{2+}}>{{V}^{2+}}>M{{n}^{2+}}\]
Correct Answer: C
Solution :
Spin only magnetic moment depends upon die number of unpaired electrons, more the number of unpaired electrons, greater will be the spin only magnetic moment. \[_{25}Mn=1{{s}^{2}},2{{s}^{2}}2{{p}^{6}},3{{s}^{2}}3{{p}^{6}}3{{d}^{5}},4{{s}^{2}}\] \[M{{n}^{2+}}=1{{s}^{2}},2{{s}^{2}}2{{p}^{6}},3{{s}^{2}}3{{p}^{6}}3{{d}^{5}},4{{s}^{o}}\]You need to login to perform this action.
