Interpretation Introduction

(a)

Interpretation: The products formed including stereochemistry for the given pericyclic reaction is to be drawn.

Concept introduction: Curved arrows aid in determining the movement and flow of electrons in the reaction. The electrons that take part in the chemical reactions are shown by the curved arrows.

Electrocyclic reactions are those in which removal of an old sigma bond and formation of new sigma bond take place. The closing of ring is a disrotatory process.

Concept introduction: Curved arrows aid in determining the movement and flow of electrons in the reaction. The electrons that take part in the chemical reactions are shown by the curved arrows.

A chemical reaction that involves [4+2] cycloaddition is called Diels-Alder reaction. The reactant molecules that give rise to the product are diene and dienophile. The rate of reaction is fast when the electronegative group is attached to dienophile. In this type of reaction, syn addition takes place.
