what is satyzeff's rule
Answers
Answer:
In organic chemistry, Zaitsev's rule is an empirical rule for predicting the favored alkene product in elimination reactions. While at the University of Kazan, Russian chemist Alexander Zaitsev studied a variety of different elimination reactions and observed a general trend in the resulting alkenes.
Answer:
Explanation:
Saytzeff’s Rule is also called Zaitsev’s rule, Saytzev’s rule or Z-rule. A Russian chemist, Alexander Zaitsev analysed different elimination reactions and observed a general pattern in the resulting alkenes. Based on this analysis, Zaitsev stated that stable alkene is formed when the removal of hydrogen from β-carbon has a low number of hydrogen substituents.
During elimination reactions, Saytzeff’s Rule comes into the picture. The most substituted product would be the most stable and most preferred one. This rule does not generalize about the product stereochemistry, but only the regiochemistry of the elimination reaction.
In organic chemistry, Zaitsev's rule (or Saytzeff's rule, Saytzev's rule) is an empirical rule for predicting the favored alkene product(s) in elimination reactions. While at the University of Kazan, Russian chemist Alexander Zaitsev studied a variety of different elimination reactions and observed a general trend in the resulting alkenes.Based on this trend, Zaitsev stated, "The alkene formed in greatest amount is the one that corresponds to removal of the hydrogen from the alpha-carbon having the fewest hydrogen substituents." For example, when 2-iodobutane is treated with alcoholic potassium hydroxide (KOH), 2-butene is the major product and 1-butene is the minor product.
Important Concept Behind Saytzeff’s Rule:
If more than one elimination product is possible, the most substituted alkene is the most stable product (major product).
