Chapter 23, Problem 91AE

(a)

Interpretation Introduction

Interpretation: A colorless complex that melts at ${\text{90}}^{\text{o}}\text{C}$ is diamagnetic is given. Various questions based on the given information are to be answered.

Concept introduction: The colour of the complex is due to the unpaired electron present in the complex.

If a complex shows diamagnetic behavior that means there is no unpaired electrons present in the complex.

To determine: The oxidation number of the given complex.

(b)

Interpretation Introduction

To determine: The electronic configuration of $\text{Cr}$

$\left[\text{Cr}{\left(\text{CO}\right)}_6\right]$ .

(c)

Interpretation Introduction

To determine: If the given ligand is a weak field or a strong field ligand.

(d)

Interpretation Introduction

To determine: The name of the given complex.
