E1 and e2 reaction ppt

Web• There are 2 kinds of elimination reactions, E1 and E2. • E2 = Elimination, Bimolecular (2nd order). Rate = k [RX] [Nu:-] E2 reactions occur when a 2°or 3°alkyl halide is treated with a strong base such as OH-, OR , NH 2-, H-, etc. E2 Reaction Mechanism The Nu:-removes an H+ from a b-carbon & the halogen leaves forming an alkene. b WebTable of Contents For E1 reaction For E2 reaction The Zaitsev Rule With E1 and E2 mechanisms we have already met, but let’s compare them now. Both are elimination reactions. When alkyl halides react with bases, the halides and hydrogen of the adjacent carbon are eliminated, and alkenes are obtained. If we have simpler alkyl halides, we …
