WebWhat is Zaitsev's rule? The more highly substituted alkene will be produced during an elimination reaction The less substituted alkene will be produced during an elimination … WebFeb 19, 2015 · Hoffmann elimination takes place when in reactant there is a poor leaving group. Fluorine is very reactive and a poor leaving group. So in fluoroalkanes, when elimination takes place a double bond comes on the less substituted side (against Zaitsev's rule or Saytzeff .)

WebCertain haloalkanes can undergo elimination in two different ways giving a mixture of two products. In such reactions, the preferred product is the more highly substituted alkene (i.e. the alkene having lesser number of hydrogens on the doubly bonded carbon atoms). This generalisation is known as Saytzeff’s rule. shirley barnett obituaryWebJan 25, 2015 · Saytzev and Hofmann elimination in E1. From what I have read, E1 largely produces the more substituted alkene because of the fact that more substituted alkenes are more stable as a result of hyperconjugation.
