Chapter 18, Problem 18.63AP

Interpretation Introduction

(a)

Interpretation:

The reaction of free radical $\text{R}·$ 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, $3-\text{hydroxy}-4-\text{methoxycinnamic}\text{acid}$ 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.
