For the given reaction, the reverse Diels-Alder reaction path has to be shown with Lewis structures of Butadiene sulfone and sulfuric acid. Concept Introduction: Diels-Alder reaction: It is the reaction of conjugated dienes with double or triple bonded compounds which are known as “dienophiles” . The reaction is a 4 + 2 cycloaddition reaction that results in the formation of a six membered cyclic product which is known as “Diels-Alder adduct” . Example: Reverse Diels-Alder reaction: It is the reverse path of the Diels-Alder reaction in which the Diels-Alder adduct gives back its corresponding Diene and Dienophile as shown here: Lewis dot structure: In the Lewis dot structure, an element will be represented by its elemental symbol. It will be surrounded by dots. Each dot represents the valence electron of that element. So the Lewis dot structure enables to represent an element with its valence electrons in chemical bonding.

Interpretation Introduction

Interpretation:

For the given reaction, the reverse Diels-Alder reaction path has to be shown with Lewis structures of Butadiene sulfone and sulfuric acid.

Concept Introduction:

Diels-Alder reaction:

It is the reaction of conjugated dienes with double or triple bonded compounds which are known as “dienophiles”. The reaction is a 4+2 cycloaddition reaction that results in the formation of a six membered cyclic product which is known as “Diels-Alder adduct”.

Example:

Reverse Diels-Alder reaction:

It is the reverse path of the Diels-Alder reaction in which the Diels-Alder adduct gives back its corresponding Diene and Dienophile as shown here:

Lewis dot structure: In the Lewis dot structure, an element will be represented by its elemental symbol. It will be surrounded by dots. Each dot represents the valence electron of that element. So the Lewis dot structure enables to represent an element with its valence electrons in chemical bonding.
