Concept explainers
(a)
Interpretation: The product of the electrocyclic reaction should be predicted.
Concept Introduction : Electrocyclic reactions are caused by either photochemical or thermal conditions. The disrotatory and conrotatory closure of the ring depends on the number of
Thermal | Photochemical | |
Four | Conrotatory | Disrotatory |
Six | Disrotatory | Conrotatory |
