Vedclass · Answer

(C) In the $3d$-series,$Manganese$ $(Mn)$ exhibits the maximum number of oxidation states,ranging from $+2$ to $+7$.$Zinc$ $(Zn)$ has a completely filled $d$-orbital $(3d^{10})$ in its ground state and its common oxidation state $(+2)$,therefore it is not considered a transition element.$Scandium$ $(Sc)$ exhibits only one oxidation state,which is $+3$.$Copper$ $(Cu^{+})$ undergoes a disproportionation reaction in an aqueous solution: $2Cu^{+}_{(aq)} \longrightarrow Cu^{2+}_{(aq)} + Cu_{(s)}$.Thus,the correct matching is: $a-iii, b-iv, c-i, d-ii$.

Aspects	Metal
$a$. The metal which reveals a maximum number of oxidation states	$i$. Scandium

$c$. 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
