Chapter 7, Problem 7.43AP
Interpretation Introduction

(a)

Interpretation:

The structure of an achiral tetramethylcyclohexane for which the chair interconversion results in identical molecules is to be predicted.

Concept introduction:

Conformation isomers are formed by the rotation about single ORGANIC CHEM +SG +SAPLING >IP<, Chapter 7, Problem 7.43AP , additional homework tip  1bond while the atoms and connectivity remains same. For cyclohexane, the most stable conformation is chair conformation in which all the carbon-hydrogen bonds are staggered. Axial bonds are above or below the plane of the ring while equatorial bonds are in the plane of the ring.

Interpretation Introduction

(b)

Interpretation:

The structure of an achiral trimethylcyclohexane with two chair forms that are conformational diastereomers is to be predicted.

Concept introduction:

Conformation isomers are formed by the rotation about single ORGANIC CHEM +SG +SAPLING >IP<, Chapter 7, Problem 7.43AP , additional homework tip  2bond while the atoms and connectivity remains same. For cyclohexane the most stable conformation is chair conformation in which all the carbon-hydrogen bonds are staggered. Axial bonds are above or below the plane of the ring while equatorial bonds are in the plane of the ring.

Interpretation Introduction

(c)

Interpretation:

The structure of a chiral trimethylcyclohexane with two chair forms that are conformational diastereomers is to be predicted.

Concept introduction:

Conformation isomers are formed by the rotation about single ORGANIC CHEM +SG +SAPLING >IP<, Chapter 7, Problem 7.43AP , additional homework tip  3bond while the atoms and connectivity remains same. For cyclohexane the most stable conformation is chair conformation in which all the carbon-hydrogen bonds are staggered. Axial bonds are above or below the plane of the ring while equatorial bonds are in the plane of the ring.

Interpretation Introduction

(d)

Interpretation:

The structure of a tetramethylcyclohexane with chair forms that are conformational enantiomers is to be predicted.

Concept introduction:

Conformation isomers are formed by the rotation about single ORGANIC CHEM +SG +SAPLING >IP<, Chapter 7, Problem 7.43AP , additional homework tip  4bond while the atoms and connectivity remains same. For cyclohexane the most stable conformation is chair conformation in which all the carbon-hydrogen bonds are staggered. Axial bonds are above or below the plane of the ring while equatorial bonds are in the plane of the ring.
