Chapter 4, Problem 38P

Interpretation Introduction

Interpretation:

The energy changes from the rotation of C2-C3 bond of 2,3-dimethylbutane and 2,2,3,3-tetramethylbutane are to be determined with all the maxima and minima.

Concept introduction:

Chair conformation: 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 equatorial position are more stable than those having at axial position.
