उत्तर
The magnetic moment of [NiCl4]2− is 2.82 BM.
Explanation:
Nickel is in the +2 oxidation state in the paramagnetic and tetrahedral complex [NiCl4]2−, and the ion has the electronic configuration 3d8. The figure depicts the hybridization scheme.
μB.M = `sqrt("n"("n" + 2))`
= `sqrt(2(2 + 2))`
= `sqrt8`
= 2.82 BM
