Chapter 21, Problem 21.140MP

Interpretation Introduction

(a)

Interpretation:

All the possible structure of the diastereomers and enantiomers of ${\text{Co(tfac)}}_{\text{3}}$ is to be determined.

Concept introduction:

The diastereomers of compound are known as the non-mirror image of the stereoisomers while an enantiomer of compound is known as the mirror- image of stereoisomers.

Interpretation Introduction

(b)

Interpretation:

The dipole moments of diastereomers A and B are 6.5D and 3.8D respectively. The diastereomers A and B are to be determined.

Concept introduction:

The dipole moment can be defined as the measurement of the separation of the two opposite electric charges.

Interpretation Introduction

(c)

Interpretation:

The activation energy of the reaction is to be determined for the isomerization reaction, $A\to B$ in chloroform solution where the first order rate of constants $0.0889h^{-1}$ at $66.1°C$ and $0.0870h^{-1}$ at $99.2°C$.

Concept introduction:

The following formula will be used −

$\ln \frac{k_1}{k_2}=\frac{-E_a}{R}\left[\frac{1}{T_2}-\frac{1}{T_1}\right]$

Interpretation Introduction

(d)

Interpretation:

The crystal filed energy level diagram for the $Co{(tfac)}_3$ is to be determined along with its magnetic properties.

Concept introduction:

The energy level diagram is used for the representation of energy shell, subshell and orbital which are occupied by the electrons of the atoms.
