Vedclass · Answer

(A) For a complex ion to absorb visible light,it must possess at least one unpaired electron to undergo $d-d$ transition.In $[Cr(NH_3)_6]^{3+}$,the oxidation state of $Cr$ is $+3$.The electronic configuration of $Cr^{3+}$ is $[Ar] \ 3d^3$.Since it has $3$ unpaired electrons,it can undergo $d-d$ transition and absorb visible light.In contrast,$Zn^{2+}$ $(3d^{10})$,$Sc^{3+}$ $(3d^0)$,and $Ti^{4+}$ $(3d^0)$ do not have unpaired electrons.

Which complex ion has the ability to absorb visible light?
