Chapter 17, Problem 17.76QP

Interpretation Introduction

Interpretation: The reason for ${\text{NiCN}}_{\text{4}}{}^{\text{2-}}$ to be diamagnetic and ${\text{NiCl}}_{\text{4}}{}^{\text{2-}}$ to be paramagnetic is to be stated.

Concept introduction: Strong ligands produce high crystal field splitting and weak ligands produce small crystal field splitting.

To determine: The reason for ${\text{NiCN}}_{\text{4}}{}^{\text{2-}}$ to be diamagnetic and ${\text{NiCl}}_{\text{4}}{}^{\text{2-}}$ to be paramagnetic.
