Question

Question: Draw the product formed (including stereochemistry) in each pericyclic reaction.

Short answer

Answer

Product of b

Step-by-step solution

Pericyclic reactions  

These reactions occur via a cyclic neutral concerted pathway. These reactions take place via the periphery of the conjugated polyene molecules.

Characteristics of pericyclic reactions  

These reactions take place via a cyclic transition state. These reactions are highly stereoselective. These reactions occur either via heat or light.
