Question

Quizplus · Accepted Answer

Diamagnetic compounds have all their electrons paired, while paramagnetic compounds have unpaired electrons. In [Zn(NH₃)₄]²⁺, Zn has a filled d-orbital and all of the ligands donate electrons to form a filled valence shell, making it diamagnetic. Similarly, in [Fe(CN)₆]^4-, Fe has a filled d-orbital and all of the ligands donate electrons to form a filled valence shell, making it diamagnetic. So, the correct answer is option C.
