Chapter 4, Problem 57PP

(a)

Interpretation Introduction

Interpretation:

The total energy cost associated with all torsional strain and steric strain of given conformations are needed to find out using table 4.6.

Concept introduction:

Conformations are arising due to the free rotation of CC bond. These rotations are measured by dihedral angle; it is the angle between two atoms attached to two different carbons of CC rotation in Newman projection.

The torsional strain between atoms of eclipsed conformations makes them more energized as compared to staggered conformations.

For eclipsed conformations, Torsional strain and steric interactions of atoms are the energizing factors.

For staggered conformations, anti-interactions and gauche interactions of atoms are the energizing factors.
