- Optical active compound 1-chloro-3-methylcyclopentane was reacting withpotassium t-butoxide in t-butanol. Two alkene products were obtained. Themain product was optically active, and the secondary product was notoptically active. What are the two products?arrow_forwardWhat product is formed when each compound undergoes thermal electrocyclic ring opening or ring closure? Label each process as conrotatory or disrotatory and clearly indicate the stereochemistry around tetrahedral stereogenic centers and double bonds. CeHs a. b.
