A) \[T{{i}^{+}},T{{i}^{3+}}\]
B) \[C{{u}^{2+}},C{{u}^{+}}\]
C) \[C{{r}^{2+}},C{{r}^{3+}}\]
D) \[{{V}^{2+}},V{{O}^{2+}}\]
Correct Answer: A
Solution :
[a] \[T{{i}^{+}},T{{i}^{3+}}\] \[T{{i}^{+}}\] is more stable than\[T{{i}^{3+}}\] because of inert pair effect and Ti belongs to group 13 and is the last element of the group. Many copper compounds are unstable in aqueous solution. Chromium compounds are more stable in acidic medium. And V shows an oxidation state of +5 only in\[V{{F}_{5}}\].You need to login to perform this action.
