$Ti^{4+}$

Vedclass · Answer

(A) $d-d$ transition is possible only in ions that have partially filled $d$-orbitals (i.e.,$d^1$ to $d^9$ configuration).$Ti^{4+}$ has an electronic configuration of $[Ar] 3d^0$. Since there are no electrons in the $d$-orbital,$d-d$ transition is not possible.$Cr^{3+}$ has a $3d^3$ configuration.$Mn^{2+}$ has a $3d^5$ configuration.$Cu^{2+}$ has a $3d^9$ configuration.Therefore,$Ti^{4+}$ is the correct answer.

In which of the following ions is $d-d$ transition not possible?
