Chapter 23, Problem 50E

(a)

Interpretation Introduction

Interpretation: If the given complexes are diamagnetic or paramagnetic is to be identified.

Concept introduction:

The complex in which the central metal ion has unpaired $\text{d}$ electrons and thus is magnetic is called paramagnetic complex and the one in which the central metal ion has no unpaired $\text{d}$ electron and thus is non magnetic is called diamagnetic complex.

To determine:

If the complex ${\left[\text{Ag}{\left({\text{NH}}_3\right)}_2\right]}^{+}$ is diamagnetic or paramagnetic.

(b)

Interpretation Introduction

To determine:

If the square planar complex ${\left[\text{Cu}{\left({\text{NH}}_3\right)}_4\right]}^{2+}$ is diamagnetic or paramagnetic.

(c)

Interpretation Introduction

To determine:

If the complex ${\left[\text{Ru}{\left(\text{bipy}\right)}_3\right]}^{2+}$ is diamagnetic or paramagnetic.

(d)

Interpretation Introduction

To determine:

If the complex ${\left[{\text{CoCl}}_{\text{4}}\right]}^{2-}$ is diamagnetic or paramagnetic.
