Which of the following statements are incorrect?A. All the transition metals except scandium form oxides which are ionic.B. The highest oxidation number corresponding to the group number in transition metal oxides is attained in to .C. Basic character increases from to to .D. dissolves in acids to give salts.E. is basic but is amphoteric.Choose the correct answer:
- AA and E only
- BB and D only
- CC and D only
- DB and C only
Solution & Step-by-step Explanation
1. A, B, and E are correct observations from transition metal chemistry.2. Statement C is incorrect: As the oxidation state of the metal increases, its acidic character increases. Thus, basicity decreases from to to .3. Statement D is incorrect: dissolves in acids to give (vanadyl) salts, not (which contains in state).
