What is the d-electron configuration of the tetrahedral complex ion [FeCl₄]^-? A) e²t³ B) e⁴t¹ C) e⁵ D) e¹t⁴ E) e³t²

Question

Quizplus · Accepted Answer

The tetrahedral complex ion [FeCl₄]^- has a d⁵ electron configuration. In a tetrahedral complex, the d-orbitals split into two sets: the e set (d_xy, d_yz, and d_xz) and the t₂ set (d_z² and d_x²-y²). The e set is lower in energy than the t₂ set. Therefore, the d⁵ electrons will occupy the e set first, giving an e⁵ configuration.
