Chapter 6, Problem 40P
Interpretation Introduction

(a)

Interpretation: The conformation which is present in higher concentration when R=CH2CH3 is to be identified.

Concept introduction: The change in Gibbs free energy is represented by ΔG°. It is a state function. The value of ΔG° depends on Keq. The free energy change is calculated as,

ΔG°=2.303RTlogKeq

If the ΔG° is greater than zero and Keq is smaller than one, then the formation of starting material is favored at equilibrium. However, if the ΔG° is smaller than zero and Keq is greater than one, the formation of product is favored at equilibrium.

Interpretation Introduction

(b)

Interpretation: The R group which shows the higher percentage of equatorial conformation at equilibrium is to be identified.

Concept introduction: The change in Gibbs free energy is represented by ΔG°. It is a state function. The value of ΔG° depends on Keq. The free energy change is calculated as,

ΔG°=2.303RTlogKeq

If the ΔG° is greater than zero and Keq is smaller than one, then the formation of starting material is favored at equilibrium. However, if the ΔG° is smaller than zero and Keq is greater than one, the formation of product is favored at equilibrium.

Interpretation Introduction

(c)

Interpretation: The R group which shows the higher percentage of axial conformation at equilibrium is to be identified.

Concept introduction: The change in Gibbs free energy is represented by ΔG°. It is a state function. The value of ΔG° depends on Keq. The free energy change is calculated as,

ΔG°=2.303RTlogKeq

If the ΔG° is greater than zero and Keq is smaller than one, then the formation of starting material is favored at equilibrium. However, if the ΔG° is smaller than zero and Keq is greater than one, the formation of product is favored at equilibrium.

Interpretation Introduction

(d)

Interpretation: The R group for which ΔG° is more negative to be identified.

Concept introduction: The change in Gibbs free energy is represented by ΔG°. It is a state function. The value of ΔG° depends on Keq. The free energy change is calculated as,

ΔG°=2.303RTlogKeq

If the ΔG° is greater than zero and Keq is smaller than one, then the formation of starting material is favored at equilibrium. However, if the ΔG° is smaller than zero and Keq is greater than one, the formation of product is favored at equilibrium.

Interpretation Introduction

(e)

Interpretation: The explanation corresponding to the relation of size of R to the amount of axial and equatorial conformation at equilibrium is to be stated.

Concept introduction: The change in Gibbs free energy is represented by ΔG°. It is a state function. The value of ΔG° depends on Keq. The free energy change is calculated as,

ΔG°=2.303RTlogKeq

If the ΔG° is greater than zero and Keq is smaller than one, then the formation of starting material is favored at equilibrium. However, if the ΔG° is smaller than zero and Keq is greater than one, the formation of product is favored at equilibrium.
