The type of cycloaddition occurs in the given reaction [1] is to be predicted. The similar product in the reaction [2] is to be drawn and whether these reactions occur in thermal or photochemical conditions is to be predicted. Concept introduction: Cycloaddition reactions are pericyclic reactions that take place in two compounds containing pi bonds to form a cyclic compound. These reactions are concerted and stereospecific in nature. According to Woodward-Hoffmann rules, the polyene containing even number of bonds in thermal conditions undergoes reaction in antrafacial fashion and polyene containing odd number of bonds undergo reaction in suprafacial fashion. The total number of bonds present in the alkenes is considered.
