Question

Which of the following crystal field diagram(s) is(are) correct for the complex given?

Short answer

1. Not correct
2. Not correct
3. correct

Step-by-step solution

Determine whether the diagram given in (a) is correct or not

The oxidation state of zinc here is 2+. The configuration is 3d¹⁰. Which should be in the order t₂g, eg. But we can observe that the order is reciprocal to the actual order. Hence, the diagram isnot correct.

Determine whether the diagram given in (b) is correct or not

The electron pair in the orbital is wrongly depicted. The paired electrons are depicted by the arrows in the opposite direction. Hence, the diagram is not correct.

Determine whether the diagram given in (c) is correct or not

The oxidation state of Ni is 2+ here. A square planner is depicted, and there is no unpaired electron. Hence, the diagram iscorrect.
