Chapter 4, Problem 52PP

(a)

Interpretation Introduction

Interpretation:

Chair conformation of given compounds should be drawn and most stable compound is needed to be predicted between them.

Concept introduction:

Chair conformer: chair conformer is a stable conformer for cyclohexane compound. In this chair conformer two positions are important for substitutions one is equatorial and other one axial position. Axial positions are parallel to the axis of ring while equatorial positions are perpendicular to the axis of the ring.

Example:
