Match the following aspects with the respective metal.
Column I
- a. The metal which reveals a maximum number of oxidation states
- b. The metal although placed in 3d block is considered not as a transition element
- c. The metal which does not exhibit variable oxidation states
- d. The metal which in +1 oxidation state in aqueous solution undergoes disproportionation
Column II
- i. Scandium
- ii. Copper
- iii. Manganese
- iv. Zinc
Correct answer: a → iii, b → iv, c → i, d → ii
Detailed Solution
The metal revealing the maximum number of oxidation states is Manganese (a-iii). The metal placed in the 3d block but not considered a transition element (due to fully filled $d^{10}$ configuration) is Zinc (b-iv). The metal that does not exhibit variable oxidation states is Scandium (c-i). The metal that in +1 oxidation state in aqueous solution undergoes disproportionation is Copper (d-ii).
