Chapter 23, Problem 8PP

Interpretation Introduction

Interpretation:

The basic ring structure of the given compound representing the different hydrogen atoms in it is to be drawn. Further, the hydrogen atoms are to be categorized as equatorial or axial.

Concept Introduction:

>

Chair conformations: It is the most stable conformation, which accurately shows the spatial arrangement of atoms.

>

Equatorial bonds are parallel to the average plane of the ring, while axial bonds are perpendicular to the average plane of the ring.

>

The conformation having bonds at the equatorial positions are more stable than those with bonds at the axial position.

>

On flipping the cyclohexane ring, axial bonds become equatorial bonds and equatorial bonds becomes axial bond.

>

Bulkier group acquires equatorial positions to form stable conformer due to steric factors

>

The organic compounds which are biologically active and consist of four ring structures arranged in a specific order are referred to as steroids. They are the derivatives of compounds of the perhydrocyclopentanophenanthrene ring system.

>

The carbon atom forms bond with the hydrogen atom, in order to complete its valency of 4, and the hydrogen atoms are regarded as axial or equatorial based on the plane in which they are present.
