The two pericyclic reactions involved in the two step process, a cycloaddition and a reverse cycloaddition are to be identified. Further how the reactions occur also is to be stated. Concept introduction: In cycloaddition reaction two unsaturated molecules add to one another to yield a cyclic product If even number of electron pair is involved then thermal reaction occur through antarafacial pathway and photochemical reactions occur through suprafacial pathway. If odd number of electron pair is involved then thermal reaction occur through suprafacial pathway and photochemical reactions occur through antarafacial pathway. To identify: The two pericyclic reactions involved in the two step process, a cycloaddition and a reverse cycloaddition and to state how they occur.
