Vedclass · Answer

(A) In a tetrahedral crystal field, the $d$-orbitals split into two sets: $e$ (lower energy) and $t_2$ (higher energy). The energy difference is $\Delta_t$. The stabilization energy $(CFSE)$ is calculated as: $	ext{CFSE} = [n_e(-0.6) + n_{t_2}(+0.4)] \Delta_t$.
For $d^2$: $e^2 t_2^0 ightarrow 2(-0.6) = -1.2 \Delta_t$ $(A-III)$.
For $d^4$: $e^2 t_2^2 ightarrow 2(-0.6) + 2(0.4) = -1.2 + 0.8 = -0.4 \Delta_t$ $(B-IV)$.
For $d^6$: $e^3 t_2^3 ightarrow 3(-0.6) + 3(0.4) = -1.8 + 1.2 = -0.6 \Delta_t$ $(C-I)$.
For $d^8$: $e^4 t_2^4 ightarrow 4(-0.6) + 4(0.4) = -2.4 + 1.6 = -0.8 \Delta_t$ $(D-II)$.
Thus, the correct match is $A-III, B-IV, C-I, D-II$.
