Vedclass · Answer

(D) $1$. $A$ transition metal ion forms colored compounds if it has partially filled $d$-orbitals (i.e., $d^1$ to $d^9$ configuration) due to $d-d$ transitions.$2$. Electronic configurations:- $Sc^{3+}$ $(Z=21)$: $[Ar] 3d^0$ (no $d$-electrons, colorless).- $Ti^{4+}$ $(Z=22)$: $[Ar] 3d^0$ (no $d$-electrons, colorless).- $Cu^{+}$ $(Z=29)$: $[Ar] 3d^{10}$ (fully filled $d$-orbitals, colorless).- $V^{3+}$ $(Z=23)$: $[Ar] 3d^2$ (partially filled $d$-orbitals, colored).$3$. Therefore, $V^{3+}$ forms colored compounds.
