The given reaction has to be identified as electro cyclic reaction, a cycloaddition reaction or a sigma tropic reaction. Concept introduction: Pericyclic reactions are “ any concerted reaction in which bonds are formed or broken in a cyclic transition state”. There is a single transition state from start to finish, in contrast to a stepwise reaction. There are mainly three types of pericyclic reactions, 1) Electrocyclic reactions 2) Cycloaddition reactions 3) Sigmatropic reactions In an electrocyclic reaction “one new sigma- bond is formed or broken.” In a cycloaddition reaction “ two new sigma-bonds are formed or broken” In a sigmatropic rearrangement reaction “ one new sigma-bond is formed as another breaks.”
