Chapter 3.14, Problem 3.23P

Interpretation Introduction

Interpretation: The structure similar to Figure $3-25$ down $\text{C}1-\text{C}6$ bond in the equatorial conformation of methylcyclohexane and the presence of equatorial methyl group anti to $\text{C}5$ is to be stated.

Concept introduction: Newman projection determines the stereochemistry of alkane. In this representation, a circle is drawn that represents the back carbon atom, while the dot represents the front carbon atom. The carbon atom that is present at the front is known as proximal carbon atom, while the carbon atom that is present at the back is known as distal carbon atom.

To determine: An explanation corresponding to the prediction of the most table isomer of decalin.
