Chapter 4, Problem 4.40P

Interpretation Introduction

Interpretation:

From the given isomer, the isomer with greater equilibrium percentage of molecules with the alkyl group in the axial position, isopropylcyclohexane or porpylcyclohexane, is to be determined and explained.

Concept introduction:

A major contribution to the strain in gauche interactions comes specifically from repulsion between the electrons on the axial group bonded to C1 and those on the axial H atoms at positions C3 and C5. There are two of these 1, 3-diaxial interactions.
