A strong crystal field produces a large value for the crystal field splitting, $\Delta$_o, while a weak crystal field produces a small crystal field splitting. Which would be more likely to put a metal ion in a high-spin configuration? A)strong field B)weak field C)left field D)right field E)center field

Question

Quizplus · Accepted Answer

In a weak crystal field, the energy required to pair electrons in a low-spin configuration is small. Therefore, it is more likely that the metal ion will adopt a high-spin configuration, which involves unpaired electrons. In a strong crystal field, the energy required to pair electrons in a low-spin configuration is large, making it more favorable for the metal ion to adopt a low-spin configuration with paired electrons.
