Interpretation Introduction

Interpretation:

When 1, 3-cyclopentadiene and p-benzoquinone are allowed to react at room temperature, a compound X is obtained. Irradiation of compound X gives compound Y (see Fig. P28.35).The structure and stereochemistry of X is to be shown and its conversion into Y is to be explained.

Concept introduction:

Generally, Cycloaddition reaction can be referred as a reaction of two different π-electron systems to form a ring product. Notably, in this reaction two new sigma bonds are formed in product with the disappearance of two fewer π-bonds. In other words, cyclo addition reaction can be best described as the reaction of number of electrons involved. In [4+2] cycloaddition one component is having four electrons and other component is having two electrons.
