$Ti^{4+}$

Vedclass · Answer

(A) $d-d$ transition is not possible in transition metal ions that have either $d^0$ or $d^{10}$ electronic configurations because there are no vacant $d$-orbitals for the electron to jump into or no electrons to excite.$Ti^{4+}$ has the configuration $[Ar] 3d^0$.$Zn^{2+}$ has the configuration $[Ar] 3d^{10}$.Since both $Ti^{4+}$ and $Zn^{2+}$ satisfy this condition,both are correct; however,in standard multiple-choice contexts for this specific question,$Ti^{4+}$ is the most common answer representing the $d^0$ case. Given the options,both $A$ and $B$ lack $d-d$ transitions.
