Chapter 24, Problem 12E

Interpretation Introduction

(a)

Interpretation:

To determine whether ${\left[\text{CrOH}{\left({\text{NH}}_{\text{3}}\right)}_{\text{5}}\right]}^{2+}$ exhibits geometrical isomerism or not.

Concept introduction:

The isomers are coordination compounds that have different arrangements of ligands but have the same formula. Their physical and chemical properties vary. There are 2 types of isomers namely stereoisomers and geometric isomers. Geometric isomers have their ligands adjacent to each other or opposite to each other.

Interpretation Introduction

(b)

Interpretation:

To explain whether ${\left[{\text{CrCl}}_{\text{2}}\left({\text{H}}_{\text{2}}\text{O}\right){\left({\text{NH}}_{\text{3}}\right)}_3\right]}^{2+}$ exhibits geometrical isomerism or not.

Concept introduction:

If the coordination compounds exhibit different arrangement of ligands but have the same formula, it is termed as isomers. Such compounds have different physical and chemical properties. Isomers are of 2 types of isomers namely stereoisomers and geometric isomers. Geometric isomers are those that have their ligands either on opposite side to each other or adjacent to each other.

Interpretation Introduction

(c)

Interpretation:

Whether ${\left[{\text{CrCl}}_{\text{2}}{\left(\text{en}\right)}_{\text{2}}\right]}^{+}$ exhibits geometrical isomerism or not needs to be explained.

Concept introduction:

Isomers are those coordination compounds which exhibit different arrangement of ligands though its formula is same. These compounds have different physical and chemical properties. There are 2 types of isomers namely stereoisomers and geometric isomers. In Geometric isomers, the ligands are arranged either on opposite sides termed as trans-isomer or on same side termed as cis isomer.

Interpretation Introduction

(c)

Interpretation:

Whether ${\left[{\text{CrCl}}_{\text{2}}{\left(\text{en}\right)}_{\text{2}}\right]}^{+}$ exhibits geometrical isomerism or not needs to be explained.

There are 2 types of isomers namely stereoisomers and geometric isomers. In Geometric isomers, the ligands are arranged either on opposite sides termed as trans-isomer or on same side termed as cis isomer.

Interpretation Introduction

(d)

Interpretation:

Whether ${\left[\text{Cr}{\left(\text{en}\right)}_{\text{3}}\right]}^{+3}$ exhibits geometrical isomerism or not needs to be explained.

Concept introduction:

Coordination compounds that have same formula but different arrangement of ligands are termed as isomers. These compounds exhibit different physical and chemical properties. Isomers exist as two types − stereoisomerism and geometric isomerism. Geometric isomers show different arrangement of ligands, namely on adjacent side of central molecule or on opposite side of central molecule.
