Match the following aspects with the respective metal.

	Aspects		Metal
(A)	The metal which reveals a maximum number of oxidation states	(i)	Scandium
(B)	The metal although placed in 3d block is considered not as a transition element	(ii)	Copper
(C)	The metal which does not exhibit variable oxidation states	(iii)	Manganese
(D)	The metal which in +1 oxidation state in aqueous solution undergoes disproportionation	(iv)	Zinc

Select the correct option :

Correct option is C

Ans.(c)

(A)  In 3d-series, Manganese shows maximum number of oxidation states i.e., (+2, to +7)

(B)  Zinc atom has completely filled d-orbitals in its ground state as well as in its oxidized state, thus it is not regarded as a transition element.

(C)  Scandium shows only one oxidation state i.e., +3.

(D) 

undergoes disproportionation reaction in aqueous solution
