| Which of the following statements is incorrect? |
A) \[S{{c}^{3+}}\] has good stability due of \[\left[ Ar \right]3{{d}^{0}}4{{s}^{0}}\] configuration.
B) \[M{{n}^{3+}}\] is more stable than \[M{{n}^{2+}}\].
C) \[C{{r}^{2+}}\] is reducing in nature.
D) Copper does not give \[{{H}_{2}}\] on reaction with dil. \[{{H}_{2}}S{{O}_{4}}\].
Correct Answer: B
Solution :
[b] \[M{{n}^{2+}}({{d}^{5}})\] is more stable than \[M{{n}^{3+}}({{d}^{4}}),\] \[E_{M{{n}^{3+}}/M{{n}^{2+}}}^{-}=+Ve\]
