Draw the line energy orbital diagram for the outer shell of an sp2 hybridized carbon atom and explain how a carbon/carbon double is formed. If we follow Hund's rule and fill each orbital with one electron and then promote one to the lone atomic p ... Tetrafluoroethylene is a reactive molecule that participates in myriad reactions. Owing to the presence of four fluorine substituents, its reactions differ strongly from the behavior of conventional alkenes such as ethylene. Tetrafluoroethylene dimerizes, giving octafluorocyclobutane. Even normal alkenes and dienes add tetrafluoroethylene in a [2+2] manner. 1,3-Butadiene gives 3-vinyl-1,1,2,2-tetrafluorocyclobutane.
