WebAnswer: According to Saytzeff’s rule, “the favoured product in dehydrohalogenation reactions is the alkene with the greatest amount of alkyl groups connected to the doubly bound carbon atoms.” Consider the following scenario: When 2-bromobutane is dehydrohalogenated, it produces two products: 1-butene and 2-butene. WebSaytzeff’s rule states that “in any dehydrohalogenation reaction, the elimination can occur in two different processes. Hence, the alkene’s preferred product has the greatest number of alkyl groups linked to the doubly bonded carbon atoms.” ink cartridges mandurah
