Here are some crystal field representations of d electrons in an octahedral field: Choose the representation that fits the transition metal atom in the following species. -[Co(NH₃)₄Br₂]⁺

Quizplus · Accepted Answer

The crystal field representation in choice B has 5 electrons in the t2g orbital and 1 electron in the eg orbital, which is the expected configuration for a transition metal ion in an octahedral field. It also matches the charge and coordination number of the complex.
