The complex FeL₆²⁺,where L is a neutral ligand,is known to be diamagnetic.The number of d electrons in this complex ion is: A)4 B)5 C)6 D)7 E)8

Question

Quizplus · Accepted Answer

The complex FeL₆²⁺ is diamagnetic, which means all its electrons are paired up. Fe is a transition metal, thus it has a d orbital. In this complex, there are two unpaired electrons in the d orbital. Hence, the number of d electrons in this complex ion is 6 (6 electrons are paired up and 2 are unpaired in the d orbital). Therefore, the correct choice is option C.
