The Zaitsev Rule, established by Alexander Zaitsev, is a principle in organic chemistry that predicts the major product in elimination reactions, favoring more substituted alkenes due to their stability. This rule is instrumental in the dehydration of alcohols and dehydrohalogenation of alkyl halides, aiding chemists in tailoring reaction conditions for desired outcomes. Understanding substitution, hyperconjugation, and the rule's application in complex mechanisms are key to its practical use in synthesis.

The Zaitsev Rule is a fundamental concept in organic chemistry that predicts the major product in elimination reactions based on the degree of substitution
The Zaitsev Rule was formulated by Russian chemist Alexander Zaitsev in 1875
The Zaitsev Rule is used to predict the major product in elimination reactions and has practical applications in chemical synthesis
The Zaitsev Rule is based on the concept of substitution, where carbon atoms in organic compounds are classified as primary, secondary, or tertiary based on the number of other carbon atoms they are bonded to
The stability of alkenes increases with the degree of substitution due to hyperconjugation, where electrons in sigma bonds delocalize into adjacent p-orbitals
The Zaitsev Rule takes into account factors such as steric hindrance and the stability of intermediates and final products
The Zaitsev Rule is used to predict the major product in elimination reactions, such as the dehydration of alcohols and dehydrohalogenation of alkyl halides
By understanding the Zaitsev Rule, chemists can tailor reaction conditions to selectively produce the desired alkene, enhancing the efficiency and specificity of synthetic pathways
The Zaitsev Rule aids in tracing the progression of products through complex reaction sequences, such as sequential elimination reactions

01
Zaitsev Rule - General Principle
In elimination reactions, the most substituted alkene is favored due to stability.
02
Alkene Substitution Classification
Alkenes are classified as primary (1°), secondary (2°), or tertiary (3°) based on bonded carbon atoms.
