A) \[T{{i}^{3+}},{{V}^{2+}},C{{r}^{3+}},M{{n}^{4+}}\]
B) \[T{{i}^{+}},{{V}^{4+}},C{{r}^{6+}},M{{n}^{7+}}\]
C) \[T{{i}^{4+}},{{V}^{3+}},C{{r}^{2+}},M{{n}^{3+}}\]
D) \[T{{i}^{2+}},{{V}^{3+}},C{{r}^{4+}},M{{n}^{5+}}\]
Correct Answer: D
Solution :
the electronic configuration of different species given in the question are: |
[a] \[{}_{22}T{{i}^{3+}}:1{{s}^{2}}2{{s}^{2}}2{{p}^{6}}3{{s}^{2}}3{{p}^{6}}3{{d}^{1}}\] |
[b] \[{}_{22}T{{i}^{+}}:1{{s}^{2}}2{{s}^{2}}2{{p}^{6}}3{{s}^{2}}3{{p}^{6}}3{{d}^{2}}4{{s}^{1}}\] |
[c] \[{}_{22}T{{i}^{4+}}:1{{s}^{2}}2{{s}^{2}}2{{p}^{6}}3{{s}^{2}}3{{p}^{6}}\] |
[d] \[{}_{22}T{{i}^{2+}}:1{{s}^{2}}2{{s}^{2}}2{{p}^{6}}3{{s}^{2}}3{{p}^{6}}3{{d}^{2}}\] |
Thus options [a] and [c] are discarded; now let us observe the second point of difference. |
\[{}_{23}{{V}^{4+}}:1{{s}^{2}}2{{s}^{2}}2{{p}^{6}}3{{s}^{2}}3{{p}^{6}}3{{d}^{1}}\] |
Thus option [b] is discarded |
\[{}_{23}{{V}^{3+}}:1{{s}^{2}}2{{s}^{2}}2{{p}^{6}}3{{s}^{2}}3{{p}^{6}}3{{d}^{2}}\] |
\[{}_{24}C{{r}^{4+}}:1{{s}^{2}}2{{s}^{2}}2{{p}^{6}}3{{s}^{2}}3{{p}^{6}}3{{d}^{2}}\] |
\[{}_{25}M{{n}^{5+}}:1{{s}^{2}}2{{s}^{2}}2{{p}^{6}}3{{s}^{2}}3{{p}^{6}}3{{d}^{2}}\] |
