Chapter 4.12, Problem 12LTS

Interpretation Introduction

Interpretation:

The possible chair conformations of given compound should be drawn.

Concept Introduction:

Conformational isomers:

• The two or more compounds have same molecular formula and different structural formulas are called conformational isomers.
• The Cyclohexane has a chair and boat conformations.
• The boat conformation of Cyclohexane is more stable than boat form.
• The boat conformations of Cyclohexane have two substituent positions which are axial and equatorial.
• The substituent occupy at similar to a vertical axis passing through the chair conformation of Cyclohexane ring is called axial position.
• The substituent occupy at similar to a horizontal axis passing through the chair conformation of Cyclohexane ring is called equatorial position.
• The two or more substituted conformations are represent by the wedges, the dark wedges are represent to upward the plain of Cyclohexane ring and light wedges are represent to downward the plain of cyclohexane.

To determine: the configuration and location of two substituents.
