If an octahedral Fe+2 complex is diamagnetic,which of the following sets of conditions best describes the complex? A) Low spin and small Δ_ο B) High spin and large Δ_ο C) Low spin and large Δ_ο D) High spin and small Δ_ο E) None of these

Question

Quizplus · Accepted Answer

Diamagnetism indicates that all electrons are paired, which means that the complex has a low spin configuration. Additionally, since the complex is octahedral, we can use the spectrochemical series to infer that a large value of Δ_ο stabilizes the low spin configuration. Therefore, the correct set of conditions is low spin and large Δ_ο, or option C.
