(a) Interpretation: The reaction of free radical R · with ferulic acid is to be sttaed. The resonance structure of the product radical is to be drawn. Concept introduction: The free radical is a molecule having unpaired electron in its molecular orbital. Due to the presence of unpaired electron the molecule become unstable and reactive. It can react with any another molecule to generate free radical.

Question

b) Certain cyclic compounds are known to be conformationally similar to carbohydrates, although they are not themselves carbohydrates. One example is Compound C shown below, which could be imagined as adopting four possible conformations. In reality, however, only one of these is particularly stable. Circle the conformation you expect to be the most stable, and provide an explanation to justify your choice. For your explanation to be both convincing and correct, it must contain not only words, but also "cartoon" orbital drawings contrasting the four structures.

Question

Chapter 18, Problem 18.63AP

Interpretation Introduction

(a)

Interpretation:

The reaction of free radical R· with ferulic acid is to be sttaed. The resonance structure of the product radical is to be drawn.

Concept introduction:

The free radical is a molecule having unpaired electron in its molecular orbital. Due to the presence of unpaired electron the molecule become unstable and reactive. It can react with any another molecule to generate free radical.

Interpretation Introduction

(b)

Interpretation:

The comparison as a free-radical inhibitor of the isomer of ferulic acid, 3−hydroxy−4−methoxycinnamic acid with ferulic acid is to be stated.

Concept introduction:

The free radical is a molecule having unpaired electron in its molecular orbital. Due to the presence of unpaired electrons the molecule become unstable and reactive. The free radical inhibitor are the substances which inhibit the reaction.
