Step 1

In compound A, which is $\mathrm{K}_2[\mathrm{Ni(CN)}_4]$, the ligand is cyanide (CN), which is a strong field ligand. In compound B, which is $\mathrm{K}_2[\mathrm{Ni(Cl)}_4]$, the ligand is chloride (Cl), which is a weak field ligand. Show more…

Key Concepts

Diamagnetism

Diamagnetism is the property of a substance wherein it creates an induced magnetic field in opposition to an applied magnetic field. This occurs when all the electrons in the material are paired, resulting in no net magnetic moment. Such substances are weakly repelled by magnetic fields.

Paramagnetism

Paramagnetism is the property of a substance that causes it to be attracted to an external magnetic field. This behavior arises due to the presence of one or more unpaired electrons, which create a net magnetic moment that aligns with the external field.

Unpaired Electrons

Unpaired electrons are electrons that reside alone in an orbital without a spin-cancelling partner. Their presence is central to magnetic behavior; materials with unpaired electrons exhibit a net magnetic moment and are typically paramagnetic, while paired electrons cancel out each other's magnetic effects, leading to diamagnetism.
