Interpretation Introduction

Interpretation:

The structure of products of the given reactions is to be determined.

Concept introduction:

The compound $p-\text{benzoquinone}$ is ubiquinone (terpene-modified quinones) obtained by the oxidation of hydroquinone. The oxidation may lead to the removal of two electrons and two protons from the hydroquinone or the loss of two hydrogen atoms.

The compound $1,4-\text{Naphthoquinone}$ is a naphthalene derivative and is an important chemical found in the vitamin ${\text{K}}_{\text{1}}$. It acts as a dienophile in the Diels-Alder reaction.

Diels-Alder reaction is a reaction that takes place between two organic compounds, such that one is a conjugated diene and the other is a substituted alkene. It is a key reaction in the synthesis of many complex compounds such as, cortisone and cholesterol.
