For each of the given sigmatropic rearrangement reactions, the type of sigmtropic rearrangement should be identified and denote by using brackets and two numbers. Concept introduction: Sigmatropic rearrangement reaction is a pericyclic reaction of polyenes ( π-system ) , in which one σ-bond is formed and another σ-bond is broken and remaining π-bonds are shifting their positions. Thereby the transition state is cyclic . The Sigmatropic rearrangement reaction is represented by using two numbers in the brackets . The numbers represent the numbers of atoms separating the σ-bond which is breaking and the σ -bond which is forming.
