Match the following aspects with the respective metal.

Aspects Metal
(a) The metal which reveals a maximum number of oxidation states (p) Scandium
(b) The metal although placed in 3d3d block is considered not as a transition element (q) Copper
(c) The metal which does not exhibit variable oxidation states (r) Manganese
(d) The metal which in +1+ 1oxidation state in aqueous solution undergoes disproportionation (s) Zinc

Options

  1. A(a)-(p), (b)-(s), (c)-(q), (d)-(r)
  2. B(a)-(r), (b)-(s), (c)-(p), (d)-(q)
  3. C(a)-(r), (b)-(p), (c)-(s), (d)-(q)
  4. D(a)-(q), (b)-(s), (c)-(p), (d)-(r)

Correct answer

B. (a)-(r), (b)-(s), (c)-(p), (d)-(q)

Step-by-step solution

In the given options The metal which reveals a maximum number of
oxidation state →Mn\to Mn

The metal although placed in 3d3d block is considered not as a transition element is →Zn\to Zn

The metal which does not exhibit variable oxidation
state is →Sc\to Sc (only +3+ 3)
The metal which in +1+ 1 oxidation state in aqueous
solution undergoes disproportionation is →Cu\to Cu
